I bought Tresemmé 7 Day Keratin Smooth after reading rave reviews on a couple of beauty blogs I follow. It wasn’t exactly cheap, but I thought well, if it works…
I have dreadful hair – thick and lots of it, but not straight and not curly. There’s a wave that if left to dry naturally shows as frizzy, so I was excited at the thought that this set of products could be the answer.
The blurb says you can use the straightening treatment without the shampoo and conditioner, but the best results are to use all three steps of the system. So I did.
According to Tresemmé, the 7-Day Keratin Smooth Heat Activated Treatment uses heat activated polymers to keep hair beautifully smooth for seven days and up to three washes. It is described as a breakthrough in hair technology, and works with the heat of your hair straighteners. And it did, that bit is certainly true – my hair was so smooth and didn’t feel heavy with product, which is good.
It’s the bit where you wash your hair again and it’s supposed to still be smooth that I have the problem with – my hair was just as frizzy as it usually is when left to its own devices. I know I’m in the minority with my opinion here – there’s lots of reviews on the Boots website for example with people simply swooning over these products – but I won’t be putting away my straighteners anytime soon.
Tresemmé 7 Day Keratin Smooth Shampoo and Conditioner, around £5.99 each; heat activated treatment, around £6.99 depending where you shop.
