Sally's Beauty sells a line called Generic Value Products that are a cheaper alternative to the more expensive big name brands. I haven't tried too many of the products but I have tried Thermal Protectant Spray and Chi Iron Guard and I will say that the generic brand is the exact same thing and provides the same overall results that you should expect in a thermal protectant spray. I use this spray on my hair when it is dry and I am going to use a curling or flat iron on my hair. When I use this product, I never get a sticky feeling on my hair nor does my hair have a funky smell after use. I have used others that had a weird smell to them that got worse after I applied heat to my hair.
The price for Generic Value Products Thermal Protection Spray is roughly about $7 and well worth it's affordable price. I would highly recommend anyone who is currently using more expensive name brand thermal heat protectant to try this brand instead.
