I recommend this product.

I'm someone who lacks the patience to wait after applying a treatment, so this is so convenient and great! My hair feels quite soft, though not quite as soft as a regular treatment. It has a nice scent, like the spray used at hair salons, and it lasts well. I have an oily scalp, so if I spray too much, my hair seems to get a bit greasy. I think I'll try the light type next time.
