Fill a spray bottle with 1/3 cup of milk. Any (fresh) milk will do but the thicker the milk is the better. Though it's questionable some believe that coconut milk has extra straightening power.
If you do use coconut milk combine it with lemon juice from half a lemon. Let it sit in the fridge for an hour until a cream forms on top. That's the stuff you want to use on your hair!
Follow the rest of the directions as normal.
You could also add a bit of honey strawberry or banana to your mixture. Just stir it up well and take in the extra moisturizing powers of the honey or fruit (and the better smell).
Powdered milk is a cheaper alternative -- and it won't go bad as quickly!
Spray the milk all over your hair. Dry or damp hair is ideal. Here's what to keep in mind:
Thoroughly saturate your entire head. You don't have half-straight half-curly hair!
Spray from root to tip being sure the tips are just as milky as the roots.
Spray on the top flip your head over and spray from the bottom. Then spray from the middle and sides especially if you have layers.
Comb tangles out of your hair with a wide-toothed comb. This keeps any of your hair from resting in a curled position and prevents any milky snarls -- that definitely won't smell good tomorrow.
Regularly massaging your scalp let it sit for 20 minutes. The milk needs time to soak into each shaft of hair and weigh it down straightening it.
This is a great time to exfoliate paint your toes or shave your legs!
Rinse out the milk and shampoo and condition as usual. Rinse your hair out a little more diligently than you normally would so you don't end up smelling like sour milk afterwards. Then continue your usual routine.
Let your hair dry. If you have somewhat wavy hair this will make your hair straighter but if you have kinky curly hair it may not work as well. However it is still nourishing and will define your waves and curls if it doesn't straighten it.
Mother Nature has her own beauty products and one of them is milk. Many believe that it has natural straightening agents that are quick and effective. Since it's probably already in your fridge why not give it a try? Save the money save damaging your hair with heat and straighten with milk. See Step 1 below to get started!
