We were seen by Anu to have the Nanokeratin Refortify system done. She was brilliant. Nice and professional. Everything went smoothly, not only the hair :) After the treatment, she explained in detail the aftercare routine. Great results, great service.

This was my first visit to Cognito this afternoon after a recommendation from my daughter. Shareefa highlighted my hair and I am delighted with it and Anu gave me a great cut and blow dry. Thank you! I now feel human again!

WOW is all I can say. After 7 years of long light hair with Shareefa and being terrified of change, we finally bit the bullet and went short and dark and I am OBSESSED. Better than I expected, I love it - thanks so much Shareefa!

My second visit to Cognito hair and this time for a colour treatment. Shareefa was knowledgeable and answered any questions I had before starting the treatment. Throughout I felt comfortable and was beyond thrilled with the final result! Am actually looking forward to my next visit . Highly recommended or as Bethanny Frankel says ... 'Don't walk .. RUN'

Great hairstylist . I had Anu at Cognito and it was my first time at this salon after my old hairdresser of 11 years had retired to the country ( Oxfordshire ) so one is often trepidatious finding a new hairdresser but Anu did a great job and I came out relaxed and happy with my hair .

Had an absolutely lovely hair cut here with Anu.I was late due to a super busy day and she made me feel relaxed and calm by the time I went home. The salon is lovely and chilled, and doesn’t have that noisy sensory overload vibe lots of places do. Looking forward to going back for my colour. Thank you!

I picked here because of its good Google reviews and I wasn't disappointed. I had an excellent hair cut with Anu, she really listened and worked with me to give me the very best option for my hair cut (my hair was quite damaged but I didn't want to go too short). She came across really honest and down to earth and I really enjoyed my visit, will certainly be back!

I went to see Shareefa because my hair has been changing and was out of control! She is really knowledgable and attentive. The saloon has a green ethos which is great … more should have. I left transformed. It isn’t cheap, but you get what you pay for! I’m looking forward to seeing how the Keune products work on my hair. Thanks for a great experience.

Shareefa has been taking care of my hair for May years now and the salon keeps improving even when you think it cannot possibly get any better. The products, the knowledge, the personal touches are always impeccable

This is my second time going to Cognito Hair hair salon, and I am extremely happy with my experience. As usual, Shareefa is knowledgeable in everything that she does, and you can tell that she knows what is best for her clients. I commend Shareefa for her knowledge and her expertise in looking after mixed-race hair! I got the Nano-Keratine treatment done to enable my curls to loosen when leaving my hair curly but also for manageability. I had gotten this same treatment done a few years ago, but I didn't remember the quality being this good! I would recommend getting this Keratin treatment done for manageability, as the outcome will leave you speechless. I am thankful for having a stylist like Shareefa, who knows how to look after any type of hair and makes me feel confident in my hair growth (which I have already noticed since my first appointment). Thank you Shareefa for the advice you give and I can't wait to continue my hair journey with you!If you are looking for a hair salon that looks after its clients and are knowledgeable in what they do, Cognito Hair is the right fit for you.

I have been going to Shareefa for 10 months now and she has transformed my hair from dark box dye red to a lovely golden caramel colour which is exactly what I wanted. I have never been more confident and happy with my hair! Shareefa is the only person I will trust with my hair now
