I have curly/frizzy course hair with thick strands but low density. Until this product, it was otherwise impossible for me to get a good blowout at home. I am just an average person that is simply unskilled with hair. This and a blowdry brush allows me to get close to salon blowout results. Not only that, the results LAST. Even when I get a professional blowout, it doesn't take but a few days for the top of my head to get frizzy and for the style to fall out. This product really does help my home blowout last and makes it easier to refresh. One would think that to do this, it would make your hair stiff and unpleasant, but it the opposite is true. Your hair is left soft, shiny, and touchable, while still retaining the style you put in it. WOW truly does describe this product.The first time I used this product, I didn't use enough of it and wasn't at all impressed. Then I read the directions, which said to apply it "liberally". I also went online and found that you need to saturate all of your strands with the product for it to work. This is a liquid spray-on, so you need to be diligent about getting all of your hair covered by working in sections and distributing it through with a detangling brush or comb. On my thick-stranded, medium-length but low density hair, I divide my hair into 3 sections and use about 8-12 sprays per section. This may be overkill, but I'd rather not risk a wash day. Given the price, having to use a lot of the product every time you use it is definitely a downside. If you want the best results, heed the instructions that tell you to spray a good amount and blowdry with tension. If you do that, being able to go many days without having to restyle your hair could make it worth the price for you. Even if you have very long or a lot of hair you should be able to get several blowouts even with liberal use for about half the cost of one professional blowout from a salon.Given my course and frizzy hair, this product works well for me, but it does make the hair slippy and soft. If you struggle with volume/texture this may not be for you. But for all you course/frizzy-headed folks out there, this is definitely worth a try.
