What kind of hair do you have? Curly, wavy, kinky?
Fantasia IC makes a great product line for all kinds of hair. They have a lot of different smoothing serums that are great for the frizzies. Depending on your hair type, you may need something with a little oil in it to provide additional moisture. They have an olive oil serum as well as ones with no oil.
And their products are not over priced.
Apply a smoothing serum to hair or plain virgin olive oil (yes, the kind you'd use for cooking) when it is wet and air dry, blow dry, or pull your hair back into a low ponytail to dry. With the use of a product you should see a lot less frizziness using any of these methods.
Aloe Vera Gel is also a great product to tame frizz. 100% Gel with no color added is the best.
You should do a deep conditioner at least twice a month or every third or forth time you wash your hair. Go to the beauty supply and get a pack of "processing caps" (these are only a few dollars per pack - they look like shower caps... or a shower cap will do). With any conditioner that you do, you can increase the effectiveness by leaving the conditioner on for a longer period of time and wearing a cap to retain the heat and moisture. It also helps to wrap a towel over the cap to keep in heat, but this isn't completely necessary.
In the salon you would condition while sitting under the dryer with a processing cap on to allow the heat to absorb into the hair follicle. So the idea is to mimic this process as much as possible.
I actually do a 2 hour conditioner sometimes, and afterwards the quality and texture of my hair is fantastic. Also make sure that you rinse the conditioner out really well... sometimes the residue from a conditiner can cause your hair to look dull or dry.
For general hair care it helps to sleep with a scarf on your hair or at least on satin pillowcases to minimize the amount of friction the hair must endure through the night. Stresses such as tight rubber bands also cause the hair to split and break which contributes to the appearance of frizz or reduces the nice shiny texture you might be going for.
