How to remove scalp keratin?

In general, scalp keratin can be removed through methods such as warm-water shampooing with scalp massage, medical treatments, chemical peels using fruit acids, microneedling therapy for the scalp, and laser treatment. Specific analyses are as follows:

1. Warm-Water Shampooing and Scalp Massage

Wash hair using water at an appropriate temperature, avoiding excessively hot or cold water that may irritate the scalp. Gently massage the scalp with fingertips while shampooing. This not only promotes blood circulation and scalp metabolism but also helps remove keratin and reduce dandruff.

2. Medical Treatment

If the scalp keratin issue is severe, medications such as selenium sulfide shampoo or ketoconazole shampoo may be used under medical supervision. Selenium sulfide shampoo effectively removes scalp keratin, while ketoconazole shampoo has antifungal properties and is suitable for thickened scalp keratin caused by fungal infections. Oral supplements such as vitamin B2 tablets or vitamin B6 tablets may also be taken to support treatment.

3. Chemical Peel with Fruit Acids (AHA)

Fruit acids reduce the adhesion between keratinocytes, promoting exfoliation of the stratum corneum and accelerating epidermal cell turnover. They also help regulate sebum secretion, thereby removing scalp keratin and cleansing the scalp. The typical reference cost for a fruit acid peel is 300–600 yuan per session. Improvement is usually seen within 1–3 weeks after treatment, although side effects such as scalp redness and stinging may occur.

4. Scalp Microneedling Therapy

Scalp microneedling creates microscopic channels in the scalp using fine needles, stimulating the scalp’s natural repair mechanisms, promoting collagen production, enhancing nutrient absorption, and accelerating keratinocyte metabolism—thus removing excess keratin and improving scalp health. The typical reference cost is 500–1,000 yuan per session. Results are generally visible within 1–2 months after treatment, though minor side effects such as pinpoint bleeding and swelling may occur.

5. Laser Treatment

Laser therapy uses photothermal effects to selectively target the scalp’s stratum corneum. The water within keratinocytes absorbs laser energy and instantly vaporizes, removing aged keratin cells. It also stimulates collagen production and enhances scalp metabolism. The typical reference cost is 800–2,000 yuan per session. Improvement is usually observed within 2–4 weeks post-treatment, though temporary mild redness and a burning sensation may occur.

It is recommended to undergo these procedures at a reputable medical facility under the guidance of a qualified physician to ensure safety and effectiveness. After treatment, maintain a clean and dry scalp, avoid scratching, refrain from using irritating shampoos in the short term, and protect the scalp from sun exposure.
