Dermatologist Who Specializes in Hair Loss Needed For Article I'm writing a piece on alopecia for HealthCentral and need a brief medical perspective from a dermatologist who specializes in hair loss for accuracy. In simple medical terms, what is alopecia, and what is happening at the hair-follicle level? What hairstyling habits can worsen hair loss or trigger alopecia in women? Are there specific chemicals (relaxers, dyes, keratin treatments) that women with alopecia should avoid? How should women with alopecia care for their scalp to reduce inflammation and support regrowth?

At the follicle level, the growth phase often shortens and the follicle can become inflamed, miniaturized, or pushed into a resting phase so it sheds hair sooner and grows finer strands over time. In autoimmune types like alopecia areata, the immune system mistakenly attacks the follicle, switching off normal growth even though the follicle is often still alive and can be reactivated with treatment. Q2 A: Very tight ponytails, braids, buns, and weaves can cause traction alopecia by pulling on the root day after day. Heavy extensions, tight wigs, and styles that always stress the same hairline area are common triggers. Excessive heat from flat irons and hot tools, harsh backcombing, and rough detangling can also worsen breakage and make underlying alopecia look more severe. Q3 A: Women with alopecia should be cautious with frequent chemical relaxers, strong bleach, and high strength permanent dyes, because these all weaken the shaft and can irritate an already sensitive scalp. Keratin treatments that release formaldehyde or similar compounds, especially with high heat, are also best avoided on fragile hair. If coloring is important, I suggest stretching the time between treatments, avoiding overlapping bleach on the same strands, and choosing gentler or semi permanent formulas after discussing with a dermatologist or experienced stylist. Q4 A: I recommend a gentle, consistent scalp routine with a mild shampoo and lukewarm water, washing often enough to keep the scalp clean but not stripped, usually every 2 to 3 days. Avoid scratching, strong fragrance, and heavy pore clogging oils on the scalp, and instead use any prescribed treatments, such as medicated lotions or foams, exactly as directed. Protective styles that are loose at the roots, silk or satin pillowcases, and sun protection for exposed areas all help reduce ongoing irritation. The big picture is to calm inflammation, protect remaining follicles, and pair good scalp care with appropriate medical therapy for the type of alopecia.
