Is keratin treatment safe for damaged hair?
Yes, modern formaldehyde-free keratin is safe for damaged hair if applied at the right strength and paired with a bond-builder like Olaplex.
Modern formaldehyde-free keratin treatments are safe for chemically damaged hair when the formula strength is matched to your hair's porosity and a bond-builder such as Olaplex is layered in. At JH Bagalur we always run a porosity check and patch test before keratin on coloured or previously straightened hair, and dial the iron temperature down to 180°C for fine or weakened strands. Results last 4–6 months with sulphate-free home care.
