Keratin Treatment in Northampton

A keratin treatment smooths the outer layer of each hair so it sits flatter, reflects more light and resists humidity. The result is hair that dries faster, frizzes far less and needs much less work with straighteners — typically for three to six months.

It is priced by length and thickness: £210 for shorter hair up to £260 for long, thick hair, because both the product and the hours in the chair grow with the amount of hair. Your stylist confirms the exact price before anything is applied.

Who A Keratin Treatment Is For

Keratin suits frizzy, coarse, thick or naturally wavy hair that takes a long time to blow-dry and puffs up the moment it meets rain. It is also popular with clients who straighten their hair every day and want to cut down on heat.

It is less useful on very fine, flat hair that already lies smooth. Smoothing it further can take away the little body it has. If that sounds like your hair, tell us at the consultation and we will say honestly whether it is worth it.

What Happens During The Appointment

Your hair is washed to lift away oil and product so the treatment can bond evenly. The keratin is applied section by section and combed through, then the hair is dried and sealed with flat irons in fine sections, which is the part that takes the most time.

Allow around three hours, a little longer for very long or thick hair. Bring something to read: most of the appointment is careful sectioning rather than waiting.

Making It Last

For the first 48 hours, don't wash your hair, tie it back tightly or tuck it behind your ears, because kinks set in easily while the treatment settles. After that, switch to a sulphate-free shampoo and conditioner. Sulphates strip the treatment far faster than anything else.

Chlorine and salt water shorten its life too, so rinse with fresh water after swimming. Clients who follow those three habits usually get to the top of the three-to-six-month range.

Semi-Permanent Blow Dry And Brazilian Keratin

You may see this treatment called a semi-permanent blow dry, a Brazilian blow dry or Brazilian keratin. The names differ, but the idea is the same: a smoothing treatment sealed into the hair with heat, which controls frizz for months. Ours is priced from £210 for shorter hair to £260 for long, thick hair.

Frizz Control That Keeps Some Movement

Frizz happens when the outer layer of the hair is rough and lets humidity in. Keratin smooths that layer, so hair dries faster, sits flatter and stays smooth in the rain. It does not flatten hair completely: waves usually soften but do not disappear.

If you want smoother hair but your ends are badly damaged, we may suggest an Olaplex treatment or a trim first, so the keratin has healthy hair to work on.
