We are proud to be the UK Ambassador for The new Crown Pro Keratin Treatment. We have finally found a keratin Treatment that can straighten even the most frizzy and curly hair types without the use of formaldehyde and lasts between 6 – 8 months. This ground breaking treatment has four individual products that can be used specifically on different parts of your hair preserving the hair’s texture, elasticity and natural shine. Your hair is made up of segments, some of which are dry, some lack moisture and nourishment and some have split ends. At the same time your roots are still healthy and nourished. Most other keratin treatments, while adequate can weigh down healthy segments with unnecessary product. The crown has devised a patent-protected method called Acro-core that is based on five smart molecules composed of natural ingredients: bio ceramide, wheat germ, mustard oil, keratin and acai juice. Every molecule has hundreds of thousands of product agents, each of which is engineered to pinpoint the segment to the hair which is needed so that it doesn’t waste it’s strength on areas that don’t require it. With this latest technology it gives the stylist complete creativity to apply these products on different segments of the hair whilst achieving the perfect results every time.

Best Brazilian Blow Dry Straightening London

What is a Brazilian Keratin Treatment or Brazilian Blow Dry?

If you have dry, frizzy hair, unruly curls or hair that’s just hard to manage then these treatments are perfect for you. We apply one of our six products specifically for your hair type and the results you want to achieve and then blow dry the treatment into the hair. We then use the irons to seal the product into the hair. Some treatments require leaving the product in for a day or two and some you can rinse straight away. Each application is different depending on your hair texture, porosity and condition of your hair and the results you want to achieve. All treatments last up to approximately 3-6 months. Those with curlier and courser hair may need to ask for a longer appointment to achieve the desired results.

When can you not have a Brazilian hair straightening treatment?

We would not recommend having a keratin treatment if your hair is very damaged. If your hair has been over bleached or over processed from other chemical treatments or from heat damage we would need to first check the elasticity and porosity of your hair. This can be done by coming in first for a consultation.

How do I take care of my hair after the treatment?

Post treatment: It’s always best to use the same products that go with the product you applied on your hair. This is because they add in all the necessary ingredients that compliment there treatment to keep it lasting as long as possible. Yes you do need to use a non sulphate shampoo on some of our treatments but this is not the only ingredient that will strip a keratin. If your hair was over processed or damaged before a treatment then it’s always best to use a hair mask instead of a conditioner as this will improve the condition of the hair giving you better results.

Hair Colour

We always advise to do your colour approximately 1-2 weeks after a keratin treatment taking into account that some colours may lift slightly. Depending on your hair, give it time to settle.
