I was so excited when I discovered TRESemme had a new range out. Once I saw the TRESemmé 7 Day Keratin Smooth at half price at Tesco, it was in my basket faster than a blogger taking food photos in a restaurant.

The 7 Day Keratin Smooth collection comes in those normal fat bottles (oh so technical!) and these smaller tubes marked with ‘expert selection’. These were a bit pricier, but I wanted the best results as my hair is wild. I call it The Bush. It’s hard to control The Bush because it basically does whatever it wants. Bad Bush.

From what I can tell, the difference between the one I bought and the cheaper version, is that the more expensive one is supposed to keep your hair smooth for 7 days, even though washes.

People pay a lot of money to have Keratin treatments done at salons, with this, you can do it in your own home without breaking your bank. In theory.

I used both bottles up before writing this. Although my hair was soft and shiny, I still had flyaways and a bit of frizz. Not as much as before, but it was still there.

I couldn’t really tell a huge difference in my hair before and after, which is a bit of a disappointment!

The Frizz Ease Flawlessly Straight shampoo and conditioner was so much better than this! You can see before and after photos in my review on it. It’s easy to see the difference between the two!

I think I’ll be sticking to John Frieda unless I find something better! I did have high hopes for the TRESemmé 7 Day Keratin Smooth but it’s just not as good!

If you do want to try it, you can buy the duo here.

What do you use to keep your hair smooth and shiny?



  1. I had the cheaper version of this, it was okay but not special. Although after I stopped using it I noticed a bit more frizz! I think serums and oils are the key to frizz more than shampoos and conditioners. Gonna check out your Frizz Ease ones now woo!

  2. Ahh so dissapointing they don’t work as well as expected! I really want to get a Keratin treatment done in a salon but they are just so expensive x

  3. My hair doesn’t need much smoothing, but I’ll keep John Frieda’s Frizz Ease in mind in case anyone ever asks for anti-frizz recommendations 🙂

  4. I need this – thanks for the honest review: my hair always has fly aways.

  5. Thats such a shame! I’ve been using the heat protectant from this line and love it! I had been alternating between the John Freida spray and the aforementioned one to decide which I liked better, and I settled on Tresemme’s. Thanks for the heads up though! xx

  6. I had the same excitement, I even followed mine with after balm to blow-dry. It was a big fat fail no noticeable difference at all. The best product I have used is the three day straight frizz ease it works wonders making my hair more manageable Lucy x

  7. Hi dear! 🙂 Your blog is so-so stlylish. Would you like to follow each other? Let me know and I am instantly follow you back. Thank your, I hope you enjoy my blog. Have a great day:) xoxo

  8. Had a look at your Frizz Ease review and it does seem more obvious. I’m not too fuss with shampoo as they seem to do similar things but I definitely notice the difference with some conditioner, treatment and serum, can’t do without! x

  9. I definitely need a smoothing shampoo in my life, will check out the John Frieda! I do like using a bit of hair oil too x
