After using the keratin sleek shampoo I use the conditioner to de tangle and soften the hair. Need to apply just a bit on the length of the hair to get the hair back in place and to get it ready for the mask. Smells so nice
Yes, I recommend this product.

Great at detangling, not so much at smoothing

I’ve been using this range for the past few weeks and it’s okay. It smells lovely and is great at detangling. However, i haven’t noticed any difference with the smoothness of my hair. I will continue to use the product but i am unsure if i would repurchase, if i did it would be for the detangling side of things rather than smoothing.

Lovely & soft

I've used this conditioner a few times now and it has definitely left my hair feeling soft and smooth and looking sleek- I wash my hair every other day, use straighteners on it and colour it once a month to cover Greys so the ends are definitely dry.
I really do think this conditioner has nourished my hair as it feels so much softer and even the ends don't have that crispy feeling. The conditioner itself was not as thick as I was expecting but it still performed well and it was easy to rinse out afterwards with no residue remaining.
Yes, I recommend this product.

Nice creamy consistency with a fruity fragrance. I didn't need to use too much of this conditioner on my hair as a little went a long way. It left my hair soft and shiny when used with the keratin sleek shampoo and spray.
Yes, I recommend this product.

I am loving this conditioner using it along with the shampoo. I can't believe the difference in my hair since I have been using this. My hair feels so much smoother and looks glossy. This smells lovely and has a good consistency. I Will definitely keep using this along with the other products in this range.
Yes, I recommend this product.

I used the shampoo and conditioner together. I found it had hardly any smell, could be improved for the experience. The bottle is easy to open even with wet hands. Left my hair feeling soft and shiny. My hair was definitly less frizzy.

Actually smooths my hair out!

Finding a conditioner that tackles frizz without leaving my hair looking flat and greasy is always a massive pain, but this one is surprisingly good. It has a nice, thick texture that coats the hair well, and it makes brushing out the tangles in the shower so much easier. Once my hair dries, it definitely feels smoother and looks a lot sleeker than usual. The squeezy tube is really handy, too, so you aren't fighting to get the last bits out. I am really pleased with how manageable my hair is after using this.
Yes, I recommend this product.
