What Is Biotin?

Biotin, also known as vitamin B7, is a water-soluble B-vitamin. It plays a role in the body's natural production of keratin, the structural protein that makes up the majority of each hair strand. In cosmetic haircare, biotin is included as a supporting ingredient in shampoo, conditioner and treatment formulas, rather than as a stand-alone treatment.

Biotin in Haircare

Biotin is a familiar name in haircare largely because of its connection to keratin production, which is why formulators add it to shampoos, conditioners and treatments as part of a broader, nutrition-focused approach to hair. Used consistently as part of a considered routine, biotin-formulated products are designed to complement the hair's own structure rather than replace it — which is also why biotin is so often paired with other actives like collagen, rather than used alone.

Benefits of Biotin for Hair

  • Supports stronger-looking hair
  • Helps reduce breakage
  • Supports healthier-looking hair
  • Helps maintain the appearance of beautiful hair

Biotin for Different Hair Types

Dry-Looking Hair

Dry-looking hair can appear dull and feel rough to the touch. Biotin-formulated products are often paired with moisture-focused actives to support a healthier-looking, smoother finish as part of a regular routine.

Fragile-Looking Hair

Hair that feels fragile or prone to snapping can benefit from formulas focused on supporting the hair's structural strength — one of the main reasons biotin is included in these formulas.

Damaged-Looking Hair

Heat styling, colouring and everyday environmental exposure can leave hair looking visibly damaged. A biotin-formulated routine, used alongside repair-focused ingredients like keratin, is designed to support the look and feel of compromised strands over time.

Normal Hair

Even hair that already looks and feels healthy benefits from ongoing nutritional support. Biotin-formulated products can be used preventatively, helping maintain the appearance of strong, healthy-looking hair.

Chemically Treated Hair

Colouring and other chemical treatments can put extra stress on hair. Biotin is often included in aftercare-style formulas to support the hair's condition following treatment, ideally alongside a gentle, colour-safe routine.

How to Use Biotin Haircare

How you use a biotin-formulated product depends on the specific LoverHair product and its instructions — a shampoo is used differently to a leave-in treatment or scalp tonic, for example. Always check the usage directions on your specific product for best results, and use it consistently as part of your regular hair care routine rather than as an occasional treatment.
