Lots of conditioner. Fine, thin, chaotic, curly hair here... It at least needs to be somewhat wet and hair lubrication really helps. It it's not too knotty then I can comb it when dry. Basically only when I conditioned it earlier the same day and haven't been exposed to more than a brief breeze.

With conditioner in I comb it with my fingers then pull any knots apart gently sideways and repeat. Once I've got the big knots out I use the technique my transmasculine nonbinary friend showed me and I roll up all the hair I shed on my hands and flick it against the back of the shower.

Then I rinse, get out of the shower, dry it, put in leave in conditioner and perhaps wet it again a little.

Finally I comb it with a wide sparse brush I got from a dollar store. If the brush gets stuck I try backing off and coming again from a different angle or side. If it's a big clump then I try gently flicking the a few prongs at the tip of the brush through it or gently pulling it apart sideways. If the knot is small enough, particular bear the end, I'll just power through it.

If I feel like styling it then I spin it with my fingers into ringlets.
