Not sure what you are looking for when you refer to it as "treats" lol. I might be able to offer some advice on preventing and helping hair loss though.
In most pharmacies there are vitamins for hair and nails. The good thing about vitamins is that that are usually natural and found in foods that we eat. These "treats" provide key nutriets to keep your hair and nails healthy without providing adverse side effects. Because most people do not receive the proper nutrients from their daily diet (especially in America), vitamins definitely help in keeping our bodies healthy. It is also the reason it is a multi-billion dollar industry. Most "treats" are consumed once a day.
If you use a lot of hair products, hot hair irons, and blow driers, be careful because a lot can kill your hair. Dying your hair especially kills your hair. It might look cool now, but as you age it will take a toll on your hair growth cycles.
Believe it or not, stress causes a disorder called Alopecia Areata which can kill all the hair on your body, including your eye brows. So if you are concerned about keeping a healthy head of hair, you might want to browse some hubs on preventing and managing stress as well.
