The TRESemmé 7 Day Smooth System is a smoothing, Keratin-infused hair care system that is supposed to keep your hair frizz-free for up to 7 days or up to 3 washes. The system includes 7 Day Keratin Smooth Shampoo, Conditioner, and Smooth Heat Activated Treatment. The key to the Smooth Heat Activated Treatment is that you have to flat iron your hair to activate the ThermaFlex technology.
I put this trio to the test and the results were good. The shampoo and conditioner smell very nice, but were otherwise unremarkable. After towel drying my hair, I applied the treatment. The box recommends you section your hair into 3-6 sections depending on thickness, and then apply 2 pumps per section. It seemed like a LOT of product because a single pump is already a good amount of product, but I followed the instructions and it proved to be ok.
Before I even flat ironed my hair I noticed my hair was less tangled than normal, and I was able to run my fingers through it without getting any snags. After flat ironing I was a little disappointed that my baby hairs just couldn’t be tamed. Otherwise, my hair felt very smooth.
My nice, frizz-free ‘do lasted about 3-4 days, not 7, and it didn’t last beyond the first wash. I understand that it says “up to” 7 days, so there’s not guarantees, but 4 days + 1 wash is fairly different from 7 days + 3 washes.
Aside from that, I was impressed though that I could go 4 full days without washing. Leave-in conditioner is usually my go-to for manageable, tangle-free hair, but it really weighs my hair down. It was nice to use a styling product that didn’t feel waxy or make my hair look greasy by day 3.
The verdict? While I don’t think it really lives up the the 7 day claim, I think the TRESemmé 7 Day Smooth System is worth a shot! If you’re hesitant to purchase the trio, at least give the Smooth Heat Activated Treatment a go. At $7.79, it’s very affordable.I received these products complimentary from Influenster for testing purposes.
