One immediate effect, a small amount to hair and they are softer on, all the frizz are disciplined and can even set up her hair. But an effect on the time also, my hair tend to lubricate faster with this kind of product, then the next day I spray them with bottled water and dried to replace them and they are perfect, fluffy and healthy. So I washed less often which is perfect for my fragile hair. Little more can use it on damp hair as on dry hair. Really happy with this product!
