We use this on my 10 month old, and it works great. We don't spend more than 2 hours in the direct sunlight with him, but will be outside off and on all day. He never gets a sunburn, and this sunscreen goes on thick so you know there is a good barrier.
This is my favorite mousse. I get perms because my hair is inconsistently wavy. The perm helps to even everything out. I use this mousse daily to help keep frizz down and hold my curls. It smells so good and I get compliments on it often, from men and women. It is easy to apply, and doesn't weigh my hair down. It also doesn't flake like some mousse do.
