Pros: works amazingly
I was so thrilled when I finally tried this method of washing hair!
i have very long, very thick, very rediculously curly hair and this works better then any expensive or shampoo/condition i've found period.
i put the baking soda in my hands and then get it wet and apply to wet hair at the roots and work it down, i add more if it feels like i need to. after i have it worked about halfway down my hair i rinse it all out.
then i take a cup of white vinegar (some use ap, i use white, the only difference i notice is the cost- the smell evaporates when the hair is dry) and i dip the end in the cup and then poor the rest over the rest of my hair and work it through with my hands.
i let is sit in for 5 minutes or so while i do something else (shave legs, clean torso, etc...) and then rinse out.
then i get out of the shower and take coconut oil and rub it around my hands until liquid and run that through my hair from the roots up. use a TINY amount of coconut oil, if you have short hair you barely need any, coconut oil is very potent, so to speak.
