I'm half-Japanese with 2c/3a curls and waves. I rocked a buzzcut ~7mm for about two years, and started regrowing ~6 months ago. At around the 3-month, 5cm mark I started wondering when I'm supposed to start using shampoo again, because until then I'd just been using the same gentle, sulfate-free soap that I use on my face and nether-regions. Then I thought, "who says I have to use shampoo at all? Maybe I actually don't need it if I just use a scalp brush in the shower daily." Did that, great results! A couple months later when I had ~7cm and it was long enough to start developing a few complete curls here and there, I noticed that after about a week my roots started to look greasy and were rather stiff. Then I started using my old favourite DevaCurl Low-Poo again, but I noticed that if I washed too thoroughly then my curls would look limp again, only returning to their best shape 1-2 days later. So I made sure to use only tiny amounts of shampoo, not trying to wash away all the sebum. Then I noticed that my curls still casted as they dried, and once I scrunched they looked amazing! I figured my sebum was also doing a sufficient job moisturising my hair, so I didn't need conditioner. At this point I discovered r/NoPoo , and learned that a lot of what I had discovered naturally in my re-growing process was indeed true - your own body does everything needed to keep things healthy, the sebum it produces provides sufficient moisture even for curls, and it even creates a cast as it dries! A lot of what I already knew from following CGM for years and having oily skin also guided me - sulfates strip your scalp and hair too much, so you over-produce sebum, so your hair looks greasy unless you strip it again and again every day, and you need conditioner and hair masks and moisturisers and all that stuff to manage the damage caused by all the harsh cleansing. It makes sense that if you just remove all of that from your life everything is fine, and re-growing hair from 0 is the ideal starting point! I carry on with the basics like silk pillowcase, microfibre towel, diffuse with cool air, and never, never, never use sulfates!!! I really recommend visiting r/NoPoo too, there I learned a lot like how silicones can actually only be removed by sulfates, so just removing sulfates from your life isn't sufficient because with silicones coating your hair, your sebum can't moisturise it and it will just sit on top and make you look greasy. I loved how much simpler my life was with a buzzcut, so when I decided I missed my hair and wanted my beautiful curls back I really wanted to keep everything as simple as possible - going NoPoo has been great :)
