It takes a bit of time (about 8 weeks) for your hair and scalp to get acclimatized.
For a while your hair feels like wool. Your hair doesn't feel that great but it does not get too oily. You have to persevere.
Now I wash my hair about every 7-10 days, it is curlier and healthier, though still dry-ish.
I used shampoo by mistake once and it felt stripped of moisture and very dry.
I did this regime after I read a book called Curly Girl by Lorraine Massey. After years of fighting my curls and straightening them and cutting my hair short to "tame" it, I now love my curls. I do have bad days, naturally but not as many as before. I haven't washed my hair with shampoo for 5-6 years now.
