I found this info out and I am going to try it tomorrow.
Great results can be achieved just as easily with a couple of handy household items and if you already own a hooded dryer, a steam treatment is well within your reach without breaking the bank! What you will need:
2 face cloths
A bowl full of hot water (not boiling)
2 plastic caps or plastic bags A
Prepare your hair first by washing and applying the conditioner or hair treatment. Soak both face cloths in the hot water. Wring some of the water out of the first face cloth. The cloth should be wet but not soaking. Place the cloth over your hair and immediately cover with one of the plastic caps/plastic bags. Wring the second face cloth and apply this over the plastic bag already on your head and immediately apply the plastic bag/cap. Ensure that the last plastic bag is tied securely around the hairline to prevent water dripping down your neck. Both bags should be spacious enough to allow the steam to form.
For the best results, sit under the hooded dryer for up to 1 hour to allow for maximum moisture penetration.
