What I Looked for Before Buying
Before I chose this spray, I paid attention to a few things:
- Whether it could protect my hair from heat styling
- If it helped reduce frizz
- Whether it made my hair feel sticky or heavy
- How easy it was to apply evenly
- If it worked well with my hair type
For me, a good heat protectant had to do more than just shield my hair. I wanted something that also improved the overall look and feel of my hair after styling.
My Experience with the Formula
What I liked most about Tresemme Keratin Smooth was the lightweight feel. I did not want a product that would weigh my hair down or make it greasy. In my experience, it sprayed on easily and spread through my hair without much effort. I also noticed that my hair felt smoother after blow-drying, which made styling easier.
How I Used It
I found the best results when I used it on damp hair before blow-drying. I also used a small amount on dry hair before using a straightener. I made sure to spray it evenly from mid-lengths to ends, since those areas usually need the most protection. For me, using too much product was unnecessary, so I kept it light and focused on coverage.

After using it regularly, I noticed my hair looked less frizzy and felt more manageable. My styling results also seemed smoother, and I felt more confident using heat tools because I knew my hair had some extra protection.
