Review (4/5): Good for feeling refreshed in-between washings
Nothing matches the clean, refreshing feeling of a good hair washing, but if you need to "freshen up" between washes, this is a great product. It smells good and I think it does make your hair feel cleaner and fresher.
Other users have complained about a lot of white powdery residue, but I haven't had this problem. Please understand that the powder is what makes this product work: you spray it on (read the instructions and don't over-spray) and then brush it through your hair and it absorbs oil and dislodges dirt to clean your hair. I did see some powder on my black hairbrush, but it wasn't a lot and it's not like it stains or is going to ruin anything, it's just powder. Most importantly, I did NOT see any of this powder in my hair or on my scalp at all. Remove your shirt before brushing it through to make sure you don't get the powder on your clothes (which I would do anyway, I don't like to brush my hair while my shirt is on because it gets hair all over it, yuck) and you won't have any problems.
This is an especially great product now that it's summer time...if you have long hair, you know that you sometimes perspire and it just feels icky, especially in the back (I wear a ponytail and that area gets extremely hot on these humid summer days). My hair is way too long to wash every day (and I have a sensitive scalp so that isn't good for it, it washes away the natural oils too much), so this is a great product to spray and brush through on hot days in-between washings just to feel a little extra clean and refreshed.
This product isn't something I need to use all of the time, but it is good to have when I need a refresher, and I have always enjoyed Garnier Fructis products.
