What everyone else said -- your hair looks like mixed 3c/4a, and very pretty. Do you typically brush down your hair and wear it out like your photos? Here are some products I use and like -- I am mostly 4a, hair around your length, with some 3c. I wear hair out 99%. Since I don't brush I need good texture definition:
Leave-in (very important for me) - Curl Junkie Hibisucus & Banana Honey Leave in (fine) or Giovanni Direct Leave-in. Both excellent.
Styling or Styling combos:
--IC Fantasia Gel(blue for color-treated, not clear) with sparkalites (can use over a leave-in or styling cream)
under Blended Beauty Styling Butter cream
(excellent, moisture-rich combo)
--Blended Beauty Styling butter cream
with drugstore gel overlayered where needed - also excellent combo
--Curls Souffle with Curl Keeper
(these go well together) - plump curls
(alone or with a drugstore gel) - great for day 2+ hair and many folks use Milkshake
as their leave-in
is a frizz reducer/eliminator, clear serum-like)
I get the best effect when I layer products.
