Lauren Baxter

Jess has been doing my extensions for some time now and I can honestly say that there is no one better! Jess is so lovely and always spends time doing your hair and talking through what aim you would like, whether it be a mix of blonds in my case or whatever look you want to achieve! Alwaysss love my hair! So soft and lightweight yet so thick! Always recommend Jess if anyone wants their hair done as I know 100% they will be happy! Best extensionist! 🙂 xx

Rachel Malone

Jess has been fitting my extensions regularly for several years now. Before this, I had experienced several hair extension disasters at the hands of inexperienced & poorly trained extension fitters so felt very apprehensive about hair extensions. Jess is very knowledgable and always attends to my concerns with care & attention. She is highly skilled at blending beautiful long extensions into even the shortest of cuts (within reason!). When assessing my lifestyle & hair type, Jess decided nail tip keratin hair extensions would be the most suitable option for me. The hair itself has always been thick, full & exquisite quality with hardly any shedding or tangling. Jess is able to add highlights, lowlights & blend other beautiful coloured looks into my hair which I love! I have very little fall out as I follow the straightforward aftercare tips given by Jess. Damage was a great concern of mine but Jess is very gentle with application & removal and so my own hair remains the same as ever (quietly growing while I enjoy gorgeous long hair). Jess is very attentive and cares about client satisfaction, she always gives 110%. I'm grateful to have found the key to long, stunning & beautiful hair. All my special occasions have been extra special because I know my gorgeous hair is turning heads! I can't recommend her work enough ❤️

Leila Marie
The here is very good quality I definitely recommend

Maryemma Lee

Absolutely love my extensions - look so natural and give me so much confidence. Thank you Ursula, would recommend to anyone. Very efficient too!

Amber Charlotte

I’m so in love with my new hair! I was corresponding with Jess prior to getting my hair fitted. Jess was so helpful, professional and provided me with all the answers to every question I had. Ursula fitted my hair and she was brilliant from start to finish! She talked me through each step throughout my fitting, styled my hair and provided me with aftercare information. The great thing about the hair is not just the service, it’s the comfort of the hair! You can’t even feel it and it looks so natural! Perfect in every way. I’ve already booked my next 2 fittings! Thank you once again! Xx
