Only Curlkeeper ever worked for me (as a leave-in); the other products are just blah.

My hair is mostly 4a. If I had to choose one product, conditioner would be key.

As a moisturizing detangling conditioner, Robert Craig is tops. Elucence Moisture Balancing #2. Suave Citrus Smoothie would be on the list if it didn't strip my color. I use Trader Joes Nourish as a condition-wash

Pre-wash deep treatments are great for me: Ojon Restorative Hair Treatment or a mix of conditioner, coconut milk, coconut oil, castor oil, honey.

Castor oil and honey are great moisture-retaining mix-ins to conditioneres or shampoos.

My current mainstay stylers are Curls/CurlyQ Milkshake and Aubrey Organics Mandarin Magic Jelly (a nice moisturizing jelly). I may switch off occasionally to Blended Beauty Curl Styling Butter and Confident Coils.

Playing with my hair is a hobby. Fluffy, fine natural 4a. Goal= Healthy, beautiful hair that retains its length.
Hear that crash? It's me falling off the CG wagon.
