Biotin for hair: what it is and honest expectations

Biotin (vitamin B7) is one of the most popular “for hair” ingredients. It is added to shampoos and sold as capsules, often with promises of faster growth. Here is what biotin can do in hair care — and what is a question for a doctor.

What biotin is

Biotin is a water-soluble B vitamin the body gets from food. It takes part in metabolism, and a pronounced deficiency can worsen the condition of skin, nails and hair. That is why biotin is associated with being a “hair vitamin”.

What biotin does in a shampoo

In a shampoo, biotin is one of the formula’s care ingredients. Shampoo is in contact with hair and scalp for a few minutes and is rinsed off, so it cannot “top up” the body with a vitamin or speed up hair growth. Its job is to be part of complete care for the lengths and scalp.

In the ORO range, biotin is in Reconstruction PRO Shampoo — together with murumuru butter, hydrolysed keratin, collagen and silk, oat and milk proteins. This shampoo cleanses and prepares dry, porous, weakened lengths for rich care.

Biotin capsules are a question for a doctor

Biotin supplements should be taken only after consulting a doctor: without a deficiency, extra biotin does not make hair thicker. High doses of biotin can also affect some laboratory test results, so tell your doctor if you take supplements.

When to see a specialist

  • hair is noticeably falling out for more than a few weeks;
  • thinning patches have appeared;
  • there is itching, dandruff or scalp redness;
  • skin or nails have worsened along with hair.

Step by step

  1. 01Choose a shampoo by your hair’s condition, not by one ingredient.
  2. 02For dry, porous, weakened lengths — Reconstruction PRO Shampoo on the scalp.
  3. 03Finish with balsam and, when needed, the Lipid & Protein Therapy mask.
  4. 04Protect lengths from heat: Active Thermo Cream before blow-drying.
  5. 05Questions of growth and hair loss — for a trichologist or dermatologist.

Common misconceptions

  • “A biotin shampoo speeds up hair growth” — a rinse-off cosmetic product doesn’t speed up growth.
  • “More biotin means thicker hair” — without a deficiency, extra biotin doesn’t affect density.
  • “Biotin treats hair loss” — hair loss has many causes; see a specialist.
  • “One right ingredient is enough” — results come from the system: cleansing, balsam, mask, heat protection.
