I really love this
This product is amazing for my super curly hair, no frizz and curls are more defined. I have used this product for 2 years now, so glad I found Kess hair and beauty, price is so reasonable compared to what I have paid in the past.
Good prices beautiful colours
This shampoo is amazing for colored hair. Also the size (1 lt) make it more affordable.
A great soap for our student food parcels. A nice treat.
This beautiful revitalizing conditioner is wonderful to use on dry hair, ensuring your hair is soft and smells quite lovely. I pair with the Angel Helichrysum Shampoo for the best results.
Kess is my go to for hair products, especially stuff that you can't find in stores. Love it!
Have been using Angel Iris for a while now but this is the first time I have used the Leave in Treatment, love it. Makes my hair feel so nice
