Glossary Hair Bleaching

chemical process lightening hair by breaking down melanin pigment

Hair bleaching is a chemical process that lightens the natural color of hair by breaking down the melanin pigment within the hair shaft. This is typically achieved using a mixture of hydrogen peroxide and ammonia, which opens the hair cuticle and allows the bleaching agents to penetrate and dissolve the color molecules. The result is lighter hair, which can range from a subtle lift in color to a platinum blonde, depending on the duration and strength of the bleaching process.

learn Hair Transplant

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.

What should I consider before getting a hair transplant? Consider your medical history, donor hair availability, and choose a qualified surgeon.
Is a hair transplant in Turkey safe? Clinics in Turkey describe their own work as safe when it is done in a licensed clinic by an experienced surgeon, and they also agree that quality varies a lot between clinics. All of that comes from the clinics themselves rather than from independent regulator or complication data, so any judgement rests on the specific clinic and surgeon, not on the country.
What are the risks and side effects of a hair transplant? Common risks include swelling, redness, infection, scarring, and temporary hair loss.
