I highly recommend this conditioner - it has given my hair life again, my hair is not dead and dull any longer. Cannot recommend this product enough
This shampoo has really helped my hair gain its life back, I cannot recommend this enough
All over my experience was very good 👍🏻👍🏻
Worth every penny. This shampoo and conditioner brought back the softness and shine to my frequently coloured hair. I wish I bought the larger conditioner size. I will next time.
This light weight curl cream leaves my hair curly and shiny with a bit of bounce.
The NAK hydrating conditioner is FANTASTIC!! It has returned the much needed moisture to my hair turning my frizz back into curls. It feels great and smell great too!!
Amazing product for styling my curly hair. Eliminates frizz and leaves hair soft not tacky. I have been using this product for a couple of years, recommended to me by my Brazilian friend and I can’t say enough about how good it is, it smells nice too.
These are really lovely products and thank-you for the freebie soap. I have only used the shampoo and conditioner once but I could feel the immediate difference that it made to my hair. I will definitely become a repeat customer
Brought the Mini Straightener as a replacement for my original. I will be using it for my upcoming travels. Most valuable and most used.
Love this product.
I’m thrilled with my Body Shop products plus the bonus treat that came with my parcel. Thank you so much Kess Hair and Beauty.
I had experienced a lot of hair loss and very sensitive scalp due to illness, Angel rosemary shampoo is very gentle, and my hair is starting to look much better, and my scalp is feeling much better. I definitely recommend the Angel products.
This is my favourite conditioner, once again great service from Kess
