Curly hair and no/low poo...

On my daughter, and to make my hairdresser feel more comfortable, I use this low poo.  Otherwise, I use either soapnuts juice or a locally handmade castille argan oil soap bar.

I use 50/50% apple cider vinegar/water as my conditioner and that's the only ratio my hair likes, but I'm only using it every 2-3 weeks so perhaps try 1/3 ACV to start, and increase your ratio until you love the results.

I also use jojoba oil to condition my ends, and tend to use a little argan oil to rehydrate the middle of my hair as needed.

I always brush before a wash, add oil or aloe and brush some more.  I tend to wear up dos to keep the oil in and protect the brushed out hair.  I also flat iron my hair so I can brush daily and oil as needed, that's how I can maintain my 21 day cleansing cycle!!

Here's why... The hair cuticle needs to be closed to be smooth, and to help keep moisture in...

Curly hair tends to be high porosity hair.  That is because to curl, the helix or spiral needs holes to bend.  By nature curly hair has lots of holes, so when wet (eg. Conditioners)  like a sponge, it soaks it all up.  But by the time it dries, the water evaporates leaving it dry again.

ACV helps to close the cuticle...

And sebum when brushed through, fills in the cuticle

Here's a response I gave to a question I got about someone struggling to be no poo with curly hair.

First things first.  No poo and curly hair are not exactly copasetic.  From both the BS use, the brushing the snarls comment I'd say that your hair isn't smooth from flat ironing because its dry and damaged.

Have no fear!  It can be healed, but it will take time.

 With hair that long, and tending toward oily, you're totally a prime candidate for luscious curls AND luxurious flat ironed locs, but here's the thing, you hair needs to be hydrated first.

I had the same problem when I starter and by fluke, realized that flat ironing could HELP me.

I ended up washing, plopping to dry and using aloe vera gel for hydration and hold (daily with a bit of water sprayed on wearing my hair curly for a week.  Then flat ironing the next weekend and with straight hair, brushing was a breeze and so was adding jojoba oil and EOs!!  I Eben figured out that argan oil is awesome too!!  I'd recommend starting with jojoba oil for hydration though.

When straight, I add oils and I brush in every direction dedicated to moving the sebum and jojoba oil through the length of my hair and making sure my end had oil too.  I mean a teensy but if oil, not a lot!  My sebum moved from at my ears (ponytail brushing) to my tips in about two months and even my curls became gloriously hydrated!!!

That makes no poo easier with curly hair.  It also made flat ironing on reduced heat possible.

When curly, I prefer brushing while wet with ACV still in.  I don't brush again unless I've wet, brushed and braided my hair so most of the detangling us done, then brush when the braid has dried.

Consider eliminating BS use on the length of your hair.  It may work marvelously at the oily roots, that's great.  You need to condition the length of your hair and treat it separately from your scalp.
