in London Pregnancy-Safe Hair Colour
At GA Salons, our 100% plant-based hair colour uses only botanical ingredients — henna, indigo, chamomile, walnut, and herbs. No ammonia, no peroxide, no PPD, and no synthetic chemicals. This makes our colour service a genuinely safe choice for expectant and nursing mothers across our Chelsea, Notting Hill, South Kensington, and Wimbledon Park salons.
Why Plant-Based Colour Is the Safest Choice During Pregnancy
The NHS recommends semi-permanent vegetable dyes such as henna as a safe alternative during pregnancy. At GA Salons, every colour formula we mix is built from plants, herbs, and flowers — the same approach the NHS considers safest. Our chemical-free formulas contain none of the ingredients that cause concern during pregnancy.
Zero Ammonia and Zero Peroxide
Ammonia opens the hair cuticle by raising pH levels, destroying tyrosine — an amino acid that helps hair hold colour and produce melanin. Peroxide strips natural pigment. Our plant-based colour works differently: the lawsone molecule in henna binds directly to keratin in the hair shaft through hydrogen, ionic, and covalent bonds, depositing colour without damaging the cuticle or cortex.
No PPD (P-Phenylenediamine)
PPD is the most common allergen in conventional hair dyes and a documented skin sensitiser. When PPD reacts with hydrogen peroxide during the colouring process, it forms Bandrowski's base — a compound shown to be strongly mutagenic in peer-reviewed research. Our formulas use henna, indigo, and botanical pigments instead.
No Resorcinol, Aminophenols, or Metallic Salts
We avoid all seven categories of synthetic chemicals commonly found in conventional dyes: ammonia, peroxide, PPD, aminophenols, resorcinol, sodium picramate, and metallic salts. Our plant ingredients are fully transparent — the only active colouring agents are botanical extracts.
No Chemical Fumes or Strong Odours
Many expectant mothers experience heightened sensitivity to smells during pregnancy. Because our formulas contain no ammonia or synthetic fragrance, there are no harsh chemical fumes during application. Clients often describe the experience as calm and pleasant — closer to a herbal treatment than a conventional colour appointment.
Strengthens Rather Than Damages
Unlike chemical dyes that penetrate and weaken the hair cortex, henna coats the cuticle with a protective layer that builds in strength with each application. Many of our pregnant clients notice their hair actually improves in condition over the course of their pregnancy. Read more about how our botanical ingredients support healthy hair.
