I have been using this Scalp Boosting Ampoule from Epais and what I like the most is that it is very easy to apply thanks to the applicator with silicone tips, which also gives a pleasant massage on the scalp. I feel that it refreshes a lot and leaves a feeling of cleanliness without greasing the hair.
What I don't like so much is that the results in hair growth or strengthening are not immediate; you have to be constant to notice changes. Also, if you're looking for something that works miracles with hair loss, this product alone probably won't be enough.
