TRESemme Keratin 7 Day Smooth System

I’ve never really looked to Keratin based products, or those that promise smoothing as I have fine hair I tend to think smoothing = flat for me. But little do I know, smoothing can actually be really good for all hair types and as much as I was in denial – I do tend to have some frizzy bits (around my hairline…there’s this one pesky bit that’s like a sullen teenager who outright refuses to do anything I ask). So when I was invited down to kick off my week with a TRESemme Keratin 7 Day Smooth System blow dry I decided why not, give it a whirl! Plus a blow dry is always a nice treat!

The system is three parts – the shampoo and conditioner, plus the heat activated treatment that promises to deliver a smoothness that lasts beyond the first wash. There are other brands on the market that promise to last for days…but the catch being that those days are only as long as you leave your hair unwashed. The difference for TRESemme Keratin 7 Day Smooth System is that it promises to last beyond a wash, as long as you use the shampoo and conditioner. All you need to do is take the time to blowdry and straighten your hair on the first wash with the three products, then wash and condition with them but no need to re-apply the treatment and your hair will be smoother than usual. Then perhaps once a week, or maybe twice if you do have exceptionally frizz-prone hair use the treatment with straighteners to ‘seal’ the frizz-fighting benefits in. Easy. I like easy products, I’m not one for lots of faff.

The good thing also being that the treatment is heat activated so does need heat – but that doesn’t mean it needs to be flat and lifeless. It can be styled curly – which is how mine was. I’m pleased to say that the style lasted just under two days (was blowdried/styled curly on the Monday, I then washed again on Wed eve) and since then with washing every other day my hair has felt smoother and my pesky cow flick easier to control.

Of course I don’t have the most severe of frizz issues at all, but I do sometimes lack shine – which I find smoothness can add to. So my hair felt shinier than usual when using these. Only downside being that my constantly sensitive scalp did feel a bit irritated by the products – but that happens with almost everything I use, so not something to judge them on at all as very much an issue with my scalp (lucky me). But to keep my hair smooth I would def consider using these, perhaps alternating with my usual scalp-friendly products to keep it under control. It would also be fab for on holiday where I could look to keep hair feeling a bit smoother and healthier than it can be after a few days of sun and sand!

    I use argan oil for shine but it can sometimes look greasy, if this works I’m definitely converting!
