The most amazing stuff I have ever used. I have thick dark brown hair and has a tendency to frizz. Once I use this product my hair was silky, smooth, and very pretty. I would highly recommend this product.

I really needed a thermal protector for when I flat iron my hair, which I do almost every 1-2 weeks. My hair is very long and it is halfway down my back. This product has such a wonderful smell. I apply it especially to my roots before and after flat ironing. It keeps my hair soft and smooth. I'm very pleased with it.

HSI's leave in hair treatment is AMAZING! I got it for Christmas two years ago and won't go a day without it! My hair has gone from dry and brittle to healthy, glossy and extremely healthy. I have tried other products but HSI is the best! My friends constantly ask me how I keep my long, colored hair so healthy (including my stylist). You won't be disappointed!

This thermal heat protector spray is just wonderful. I have used John Frieda for years and I thought it was the best. Until I tried this. I will be changing my protector spray to HSI thermal spray. I was so pleased when I straightened my hair with this. It came out smooth and shiny. Really really pleased with this spray. It has a great smell and is a huge bottle so it is worth the money. I would recommend this thermal spray. Sample received for an honest and unbiased review.

I've used a lot of thermal protectors and this truly is a great one. Man, compared to the other one's I've used this is a runaway favorite. For one, the spray top is EXCELLENT. It does a great job of diffusing the product onto the hair... there's even coverage and just the right amount of coverage when it sprays out. Also, is does a great job of protection and shine. I can't give this one enough praise, buy it, try it!

I want to start by saying this brand is absolute the best I've ever tried. My hair is super curly and it leaves my hair silky smooth and when I straighten it, it lasts for hours! I love this product and I will definitely buy it again and again. It's one of the few that have actually worked on my curly hair. I actually purchased the entire HSI line (shampoo, conditioner, argan oil, blow dryer and flat iron). It's hands down the best I've ever used and I recommended it to everyone.
