Last washed my hair on Sunday and it's dryish is this normal?

I CO wash, and my hair no longer gets greasy. I only wash around every 10 days or so, if I use shampoo I notice my hair is greasy very quickly (within a couple of days) Shampoo also makes my hair horribly dry and frizzy, which is why I don't use it. Try just rinsing with water after running, or adding conditioner to dilute your shampoo. Always mix your shampoo with water in a jug before applying to your hair, you will need a lot less.  Then try replacing half with conditioner, then three quarters and so on.Your hair takes a while to adapt to less shampoo, but the results are worth it IMO.

I CO wash also, every 7-10 days. Sometimes I CO wash it before that though, like if I'm going out and I have a bunch of kinks and creases in my hair from sleeping. When I do that though, I always do an overnight coconut oil soak the night before, or else my hair will feel dry. I love CO washing + I don't imagine myself ever switching back to shampoo, ever, but now when I do wash or need to shampoo to clarify it, it feels like it gets much dryer than when I used shampoo on a normal basis, plus my hair is bleached now so I'm sure that factors into it as well.

Bleached hair IMO seems to just act + respond differently to routines/products than hair that isn't bleached, or hair that is just lightly processed (like with just demis, or permanent with 10 vol), especially the older/longer the hair because it's already been through more mechanical damage like brushing/combing knots and tangles, styling, the wind, etc..Like, all of my hair that I still have after having to give it trims from bleach damage, split ends from dull shears and whatnot, has only been bleached once. All of the hair that was bleached 2-3 times has been all cut off. The hair that was bleached more times responded very, very differently to leaving split ends on my hair than when I left split ends on my hair when it was only processed with a demi. Before when it was just with demis + if I had split ends + left them for a month, I would maybe need to cut off a half inch at the most. With my hair that was bleached 2-3 times, I left it for 2 months (because I didn't have the extra money to get them sharpened) and I had to cut off between 2-3 inches! It was awful.

With bleached hair too, I think it is much more prone to get drier than if it wasn't bleached or it was processed less. I would do more overnight coconut/argan oil soaks, and remove them with conditioner in the morning instead. Just coat the hair in conditioner and leave it for a half hour or more, then rinse in warm water. I find a thinner silicone free conditioner like Suave's Tropical Coconut works well at removing it, a lot better than using shampoo.

I would use a sulphate free shampoo if you're not already too. And instead of shampooing your hair every time, just try scrubbing a thin silicone free conditioner on your scalp instead, or diluting your shampoo like WP suggested. Ideally I think CO washing would benefit you a lot. There's a good summary of it here:

And a thread about silicones, which would be good to read through if you do decide to CO wash:

I CO wash also, every 7-10 days.

Good! 😀 Makes me happy to know I am not a dirty mess for not washing my hair too often, it just doesn't need that!

I went years washing my hair every single day using shampoo and conditioner each time and it always looked and felt great.  I think the brand of products you're using makes a big difference.  UNTIL I went overboard dying it too often that is, now I go 2 to 3 days at a time (which feels like a long time to me) and often just do a conditioner only wash.    My hair has never been oily because it's naturally dry but I just don't like the way it feels or smells after a few days.
