There are many different products for shine from spray to a serum. It can be applied on dry hair as well as on wet hair. For fine hair a spray is best and very little as it can weight the hair down. For coarser texture the serum as well as the spray can be used.
Some shine products are best used on wet hair before blowdrying and even help to straighten the hair.
Adding shine is one of those things most hair products promise but only a some are created only for the purpose of adding shine and work best.Hair serum is one of the products that is used only for shine. This product has the advantage of also filling the hair if the hair is dry but this is secondary result to shine. There are also some shine pomades that are solid but once in touch with the hands will melt into a serum. The trick to using most shine products is to start by using very little at first and add more if you need. If you use too much the hair can seem dirty and one has to start all over again by shampooing.
If hair has a build up of a heavy product remember to use baby powder on dry hair before shampooing to get it out completely.
