Why biotin

Keratin from within

Biotin (vitamin B7) supports enzymes involved in keratin production — the protein that gives hair its structure and nails their strength.

Hair thickness

Often chosen by clients with thinning or fragile hair who want targeted nutritional support.

Nail strength

Helps address brittle or splitting nails when biotin deficiency may be a factor.

Skin barrier

Supports healthier skin from within — useful alongside facial or scalp treatment plans.

Direct delivery

Injection provides efficient supplementation when diet or oral biotin alone is not enough.

FAQs

Common questions

Will biotin regrow my hair?

Biotin supports keratin and hair structure when deficiency or poor nutritional status is a factor. It is not a cure for all types of hair loss — we set realistic expectations at consultation.

How often should I have biotin injections?

Many clients book every 4–8 weeks during an active phase. Your clinician will recommend spacing based on your hair goals and other treatments.

Can biotin help my nails and skin too?

Yes — biotin is commonly used for brittle nails and skin barrier support as well as hair, which is why it sits in both our hair and skin menus.

Is biotin safe with other medications?

Tell us about all supplements and prescriptions at your visit. We check for interactions and suitability before treatment.

Injection vs biotin tablets?

Injections deliver biotin efficiently without relying on daily high-dose oral supplements, which some clients find easier to maintain.
