I like Schwarzkopf products but this is just ok.

I generally like Schwarzkopf products especially their salon products and this is a light weight dry shampoo blends will into my hair. The Schwarzkopf Styliste Ultime Biotin+ Volume Dry Shampoo does a okay job of freshing up the hair,but I not sure how much biotin in the product to notice it making difference to my hair. It also has a baby powder scent which is personally not my favourite.

Excellent and Effective

This dry shampoo is hands down one of the best I've ever used. Firstly, it's very effective in removing grease and adds volume to my flat hair. It does not leave any white residue and it is easily brushed/combed/fluffed out. It does not leave my hair feeling stiff/sticky or weighed down. The can has easily lasted me a few months and that's with using it once per week. I've used it after 3 days without a wash and my hair looks like it was just washed that same day.
The only reason why I didn't give the rating a 5/5 is because of the strong smell. It's somewhat pleasant and sort of smells mildly masculine to me, I dislike masculine scents unless it's on men.

I would have bought this again, but sadly I cannot find it at Walmart anymore :(
