So! It's been 2 months since I quit shampooing my hair. Verdict... I love it! I can't say that I don't get greasy hair but I'm learning how to hide it.
I usually shower and "wash" my hair every 4-5 days - I scrub my roots just with water, and then I do a Keratin Treatment followed by conditioner. I know people that don't shampoo typically don't use conditioner either, but my hair is very dry and fragile from lightening my ends so I really need the extra moisture, help to repair those strands, and to get those tangles out without ripping half my head of hair out.
After the shower I spray Keratin Oil on my ends and let it air dry. Once its dry it is acutally kind of scary because the roots still look wet.... I apply dry shampoo to my roots - lifting up the hair on either side of my part and spraying it underneath then rubbing and brushing it in until it is completely absorbed. I only have to do dry shampoo the first day after washing and then I'm usually good for the rest of the 4-5 days.
I have definitely noticed that my hair is growing way faster these past two months, and that is the main reason I am doing this. Because I want my hair to be healthy enough to growwwww long! So I am definitely going to keep up with the no shampoo.
