How Long Does a Keratin Treatment Last? (And How to Make It Last Longer)

It's the first question almost everyone asks about keratin treatments in Gloucester: how long will the results actually last? The honest answer is usually three to four months, but the range is wide, and most of what decides it happens after you leave the salon.

What affects how long keratin lasts?

Wash frequency is the biggest factor. Every wash gradually lifts the treatment, so clients who wash daily see results fade faster than those who wash two or three times a week.

Your products matter just as much. Sulphate shampoos strip keratin quickly. Switching to a sulphate-free shampoo and conditioner is the single best thing you can do to protect your investment.

Heat, chlorine and salt water also shorten the lifespan, so use heat protection and rinse hair after swimming.

Keratin vs Hair Botox: what's the difference?

Keratin treatments focus on smoothing: they seal the cuticle, cut frizz dramatically and make blow-drying faster. Hair Botox is a deep-repair treatment: it fills and nourishes damaged strands, adding softness and shine without straightening the natural texture as much.

Both last a similar amount of time, and both work beautifully on colour-treated hair. Which one is right depends on whether your priority is smoothness or repair, something we assess in your consultation.

Making it last: the simple rules

Wait the advised time before your first wash, use sulphate-free products, wash less often, and sleep on a silk or satin pillowcase if you can. Clients who follow these rules regularly stretch their results to the four-month mark and beyond.
