It’s a bit tricky to figure out if this should be applied to the scalp or the ends of the hair. The directions are not too clear (in English). From my experience though (I purchased the entire line) the spray in for the scalp is more bang for your buck because you get more product to put in your scalp for the hair loss. This is a small tube. I do really like the ingredients though, there are several peptides in it and centers and menthol which increases oxygen in the scalp which can help with hair growth.
