I haven't shampooed my hair in over a year.
No, this doesn't mean I have not washed it. I've been doing the "no poo" method.
A little over a year and a half ago I increased a dosage of a medication that can make your hair fall out as a side effect. I was losing hair all over the place and worried about it getting thinner. I read about different vitamins you could take or products you could buy but none of them seemed convincing for me (not to mention expensive).
I discovered the no-poo method by chance on pinterest. I read a very detailed account on why shampoo is bad for your scalp and how to no-poo wash your hair from Code Red Hat. And it has been awesome for me. Not only do I feel great about reducing the amount of chemicals I put on my body and down the drain- I also don't need to wash my hair as often, and it has gotten thicker! And it is way cheaper than shampoo.
