If you get a sore or scar on your scalp does it always cause permanent hair loss?

Posted on by Jodi LoGerfo

Question:  I've noticed more hair fall out than usual recently, so, upon looking at my scalp and feeling around more closely, I've found several different areas with  around my scalp where there is no hair. Some areas of hair loss feel smooth with no hair in them and some are sensitive and painful, as if a sore is there or has healed. HELP!

Answer: Clinically, we call that cicatricial alopecia which is the medical term for hair loss due to scarring. Since scars, sores or inflammation  occur due to many different causes, you should head directly to your dermatologist so you can have your scalp examined and a diagnosis made.

The sooner you figure out the the source, the sooner you can begin treatment to cure any lesions (sores) so they don't scar and cause permanent hair loss.

Once hair loss occurs, hair does not usually grow back because the scar tissue has killed the hair follicle. 

How we diagnose cicatrical alopecia, or scarring alopecia 

It's a process that starts with many questions. We will ask you about any recent illnesses, injuries, allergies, your lifestyle, medications and your haircare regimen. We will closely examine your scalp using a magnifying glass and a special light to determine if the lesions have bacterial or fungal causes. We will feel your entire scalp and any lesions feeling for inflammation, sores or scales to determine the exact nature of the lesions and how they appear at different stages and locations. We will also document any hair loss that has occurred and take pictures for future reference. Often, we will take a biopsy of the sore or scarred area to determine the exact cause (if bacterial or fungal) and also to examine the health of the hair follicles to ascertain the severity of the condition. (We use a 4mm punch biopsy to provide an adequate specimen from an active lesion. Sometimes we will also take another sample from an unscarred area.)

Any type of scalp reaction or injury resulting in a lesion that causes a scar can cause death to the hair follicles and permanent hair loss and we call that scarring alopecia. Lesions that cause scars and hair loss can be caused by any of the following conditions and diseases: 


  • Discoid lupus erythematosus (DLE): A chronic skin condition characterized by inflamed sores that begin as  a red, inflamed patch with a scaly and/or crusty look and feel. The patches leave noticeably discolored, raised scars. Hair follicles are damaged first by the sores and then the resulting scar tissue causes permanent hair loss.
  • Lichen planopilaris: Also called follicular lichen planus, this a rare inflammatory condition results in patchy progressive permanent hair loss. Initially you may notice some small or spiny red bumps around involved follicles which may or may not be itchy. This eventually forms larger reddish lesions (resembling a lichen pattern) and scar tissue which damages hair follicles and causes hair to fall out and not grow back. Additionally, Frontal Fibrosing
  • Alopecia: appears to be a variant of lichen planopilaris. This occurs in mostly older women and appears in a band-like pattern in the frontal and temporal areas of the scalp. Often, a patient's eyebrows are also affected.
  • Sarcoidosis: This disease, also with unknown origin,  causes collections of mixed inflammatory cells (granulomas) which form lesions resulting in scarring at many different parts of the body, including the scalp.


  • Seborrheic dermatitis: We believe this condition is an inflammatory reaction related to an over-abundance of a normal  yeast species  found on the scalp called M. globosa. It produces toxic substances that irritate the scalp causing a scaly rash.
  • Ringworm (tinea capitis): On the scalp, this common fungal infection characterized by itchy red rings can result in scaling and hair loss  in children, and can progress to folliculitis, too (see below).


  • Folliculitis decalvans: Simple folliculitis is any bacterial infection of the hair follicles. But when hair loss is caused by  redness, swelling and pustules surrounding hair follicles that appears to be spreading, it is called folliculitis decalvans. Another type of scarring alopecia, hairs shed as follicles are completely destroyed by the inflammation. A resulting scar is left behind where hair will no longer grow.  Simple folliculitis (one sore) can stem  from a bug bite or a scratch and flare-up or spread if infected with the bacteria Staphylococcus Aureus but recently we have found Methicillin Resistant Staphylococcus Aureus (MRSA) in some lesions and boils, so we always want to take a culture in any open lesions on the scalp, especially those that are spreading. In addition, a variant of folliculitis decalvans occurs in African Americans who present with ingrown hairs of the beard (pseudofolliculitis), acne keloidalis (a destructive folliculitis of the back of the scalp) and scarring alopecia.


  • Central Centrifugal Cicatricial Alopecia (CCCA): Usually seen in African American women, this type of scarring alopecia usually develops on the crown and spreads peripherally to form a large oval of hair loss on the scalp. Originally, this type of hair loss was thought to be caused by hair straightening with a hot comb or due to the hot petrolatum used with the iron; however, was also found to take place in patients without the use of hot combs or straightening methods.

How we aggressively treat lesions that cause scars…

Once we know what may be causing the lesions, we can treat them to minimize spreading, scarring and any resulting hair loss, using any of the following treatments or combinations of treatments:  

    • Oral and intra-lesional steroids
    • Topical corticosteroids
    • Oral retinoids (isotretinoin)
    • Antimalarials (hydroxychloroquine)
    • Antibiotics (tetracycline, doxycycline, minocycline)
    • Antifungals (itraconazole)
    • pioglitazone
    • Immunosuppressants (cyclosporine, mycophenolate mofetil)
    • DHT blockers (dutasteride internally and minxoidil topically to -induce hair growth if follicles are alive.)

I have found that most patients experience hair loss very gradually (and cannot see the back and top of their head) and the prolonged course of the disease may cause a lack of necessary action. You need to know that the progressive destruction of hairs will result in ever-expanding areas of permanent hair loss. So, no matter what, go see a dermatologist as soon as you feel any sores, pimples, pustules, pain, itchiness, scaliness or inflammation on your scalp, whether or not they have already caused hair loss, because they need to be treated ASAP and aggressively as possible. 


Are you making these top sunscreen mistakes?

Posted on by Jodi LoGerfo

 Question: I recently went out for a day on a boat with friends and even though I used SPF 50 sunscreen all day, I still got burned. What did I do wrong? Answer: There's a lot of news in sunscreen ingredients and thinking these days so lets update how you buy, use and apply sunscreen so you don't get burned again (or needlessly exposed to the rays that cause aging, wrinkles and skin cancer): Mistake:  Not applying enough sunscreen The current guideline is to apply a shot glass-worth, one full ounce, of sunscreen to your body when spending the day in the dun. And, the most important part, you should reapply this amount of sunscreen  every two hours regardless of the SPF noted on the bottle, so you could go through half of an eight-ounce bottle in one day in the sun! Mistake:  Believing that sunscreens are "water-proof" The FDA, in its new labeling guidelines, has declared that the use of the term "water-proof"  misleading and banned brands from using it. The word will need to be removed from labels by December 2012.  Now, the guideline is that sunscreen is "water-resistant" and only for a tested time limit of 40 or 80 minutes when spending time in the water, after which the product will need to be re-applied. Mistake: Applying the sunscreen when you get there The best way to allow sunscreen to do it's work is to apply it a full 30 minutes before going into the sun, so it has time to bond to skin, instead of getting immediately rubbed off by a towel you lay on or washed off by jumping directly into the water. Mistake:  Not protecting your skin from UVA rays It used to be that sunscreens only protected against UVB (the burning rays) but now a slew of new chemicals can absorb UVA rays (the ones that penetrate deeper to cause aging, wrinkles and skin cancer).  Choose a sunscreen with the new designation "broad spectrum" because these have been tested by the FDA to provide protection against both UVB and UVA rays. Consumer Reports recently tested and rated sunscreens according to the new FDA labeling requirements and found these three top-rated choices:

  • All Terrain AquaSport SPF 30 (for athletes and outdoor workers)
  • Coppertone Sport High Performance Ultra Sweatproof SPF 30 (for athletes and outdoor workers)
  • No-Ad with Aloe and Vitamin E SPF 45 (for the budget minded, every-day body user)

Mistake:  Thinking the higher the SPF, the better the protection… According to Consumer Report's recent ratings, top-rated sunscreens are between SPF 30-45. The new thinking is that higher SPF does not really not afford more protection. Here's why:  an SPF 15 filters out approximately 93% of all incoming UVB rays, SPF 30 filters out approximately 97% and SPF 50 filters out approximately 98%. No sunscreen can block out 100% (which is why the FDA has also banned the use of the word "sunblock" on labels) of all UV rays so after an SPF 30, you can see the difference in filtering is negligible. The old  thinking:  If your skin starts reddening in 20 minutes when exposed unprotected to sunlight, using an SPF 15 should prevent your skin from turning red for 15 times longer (approximately 5 hours). The new thinking: No sunscreen protection lasts more than 2 hours. Choose an SPF 30-45 and reapply one ounce every two hours for real protection. Mistake:  Ignoring your scalp Most people protect their eyes with sunglasses and slather on the sunscreen but completely ignore their scalp. This is very dangerous, especially if you have any hair loss or thinning issues. Apply sunscreen to any areas experiencing hair loss (a widening part-line, bald spot or receding hair line) and definitely wear a hat! Mistake:  Believing that the sun does not affect your face every day I advise everybody to apply a basic "broad-spectrum" sunscreen every day to face, underneath makeup or in makeup for women,  especially to protect against photo-aging and skin cancer that you cannot see happening. One that I personally recommend, that was also recommended by the Consumer Reports Ratings, is La Roche-Posey Anthelios 40 with Mexoryl SX SPF 40. Have you made any of the mistakes on this list recently? Tell us your worst sunburn story in the comments!

A word (maybe more than one) on hair conditioning…

Posted on by Jodi LoGerfo

 The primary purpose of hair conditioning products is to reduce the resistance that occurs when hair (particularly wet hair) is combed or brushed.  Conditioning agents lubricate the hair fiber so that surface friction is diminished and hair becomes easier to comb through.  The hair feels softer, more moisturized, more manageable, and “flyaway” hair is tamed.  In addition, increased ease-of-combing means that hair fibers can be aligned in a more parallel configuration, thus improving  the appearance of  hair shine. Hair conditioners work by protecting the hair’s structural elements, especially the cuticle, from grooming damage, which is probably the most significant source of damage to the hair surface.  Excessive combing and brushing without conditioning can chip and tear away the cells of the hair cuticle.  The ends of the hair fiber are subject to greatest damage because the tips are older and have been exposed to more combing, brushing and stress as a result of the detangling process.  Without sufficient conditioning, the cuticle layer, particularly on hair tips, is eventually lost, causing split ends.  Keep in mind that hair is at its most fragile when wet, and combing wet hair can cause maximum damage to the cuticle cells; therefore it is particularly important to condition hair at this stage of grooming. Conditioners also help combat another prevalent cause of damage to the hair: the use of grooming appliances such as blow dryers, curling irons and heated rollers.  Some appliances reach temperatures of 200 to 400°F and can cause steam to be released from the hair fiber, resulting in bubbling and buckling of the cuticle, especially if hair is not completely dry while being styled.  Conditioners protect the hair from heat damage, and certain conditioning polymers can provide extra protection from heat and increase the life of a hair fiber. Finally, regular use of conditioner helps maintain the integrity of cuticle cells in hair that has been chemically processed.  In healthy “virgin” hair (i.e., hair that has not been chemically processed), the cuticle surface is hydrophobic, because there is a layer of fatty acids covalently bonded to the outermost surface (epicuticle) of the hair. On the other hand, hair that is chemically treated (e.g., with bleaching, dyeing, perming or straightening agents) is compromised because these chemical treatments include oxidative steps that modify and strip the surface of the hair. Chemical treatments increase surface friction, causing greater resistance to combing and making hair feel rough and dry.  Because of this increased likelihood of grooming damage, treated hair generally requires more conditioning than “virgin” hair. I hope you find this information useful. Often patients come into our office with hair loss. Sometimes, there is significant hair breakage which can be easily remedied if you smooth hair’s outer cuticle. Conditioning your hair will help your hair look healthy and shiny. It is worth doing! Happy Easter! Happy Passover!

Are you pulling your hair out?

Posted on by Jodi LoGerfo

Question:  Can I be causing my own hair loss problem? I have a habit of tugging and twisting on individual hairs every day and even pulling some out and I've noticed some spots where my hair seems to be thinning. What should I do?

Answer: Well, its sounds like Trichotillomania.

This is actually a hair loss disease, but it is psychological in nature rather than physical. The disease is pronounced: trik- oh-till-oh-may-nee-ah. People also call it ‘Trich’ or TTM for short. I can tell if a patient is suffering from this disease rather than something physical such as pattern baldness or auto-immune such as alopecia areata because  if I feel stubble in the bald spots, it tells me that hair is growing back normally, although it might have been removed.  Bald patches of alopecia areata feel smooth and so do pattern baldness spots because hair is not growing back normally and the growth cycle is disrupted for a physical reason. I suggest a visit to a dermatologist to get an accurate diagnosis. It's a compulsion to pull your hair out…literally. If you feel a strong compulsion to pull out hairs, as you said, you may very well be causing your hair loss. In some patients, the compulsion to pull at hairs is so strong, they feel they can't stop, but others can learn to control it through awareness or will power. Trich does not affect everyone who suffers from it the same way or to the same degree. Some pull hair deliberately and some pull hair out unconsciously and some people pull only scalp hair while others may pull facial hair such as eyelashes and eyebrows or body hair on legs and arms. Some patients pull any and all hair. Some Trich patients just pick up hairs and roll them between fingers. Hair loss can become permanent The longer the hair pulling and twisting habit goes on, the more severe the hair loss may be. In extreme cases, hair loss can become permanent because hair follicles can become damaged to the point of death. In milder cases, hair keeps re-growing, although eyelashes and eyebrows take a notoriously long time to grow back. A dermatologist can confirm the health of hair follicles and a prognosis for hair re-growth.

  • What's the prognosis and treatment for Trich? Researchers are unsure how the compulsion to pull out hair starts.
  • Past statistics on the disease show that Trich can strike happy, well-adjusted people as often as emotionally disturbed or depressed people. these same statistics show that Trich behavior usually starts in early adolescence and that 90 percent of sufferers are women.
  • I think that the statistics may be a little more skewed towards women because Trich is a less satisfying compulsion and less noticeable in men with short hair and male pattern baldness and maybe less men seek medical attention for such a habit. Current research on Trich shows that  similar brain chemical imbalances that cause depression or bulimia can cause Trich behavior and treatment with anti-depressant medications may help curb the compulsion to pull at hairs and allow hair to grow back. A Psychologist can help you determine your best course of action once a diagnosis is made.
