Melanotan 2 and Hair Colour: What Can Be Claimed?

Visitors sometimes ask whether Melanotan 2 will darken head hair, roots or grey hair. A claim about darker-looking skin does not establish a predictable change in hair colour. This article separates those questions and explains why confident colour and timing promises are not supported by the guidance cited here.

Skin pigmentation is a different question

Cancer Research UK describes Melanotan as a product that can stimulate pigment cells and make skin appear darker. Its guidance does not provide a reliable shade chart, success rate or timeframe for scalp hair. It would be misleading to turn a statement about skin appearance into “most people’s hair becomes several shades darker.”

A before-and-after photo also cannot establish what caused a change in hair appearance, including lighting, dye or a naturally changing colour. A product claim about hair needs evidence for the exact outcome, not an analogy to skin.

What about grey hair or a two-week promise?

The old claims that grey hair will not respond, that visible changes start after one or two weeks, or that particular shades are likely cannot be established from the cited UK guidance. This page therefore gives no hair-colour timetable or prediction for an individual.

Safety claims need their own evidence

Cancer Research UK advises against Melanotan nasal sprays and injections and says they have not been tested for safety, quality or effectiveness. the MHRA’s Melanotan II response also explains the safeguards missing from unauthorised products. Neither a hoped-for hair effect nor an online testimonial changes that assessment.
