It's only as confusing as you want it to be. It's like skincare - you can wash your face with soap and slap some nivea on, or you can use 15 different products. They're both skincare routines.
Just avoid sulphates, silicones and drying alcohols. And ideally don't brush your hair or use a normal towel to dry it.
Join one of the fb groups and you'll get loads of hints and tips. You'll read lots of suggestions from deep masks to rice water rinses and different techniques, but tune most of that out and start simple. And there's no need for a final wash - just get conditioner and gel and start straight away.
I co-wash (scrub my hair clean with conditioner) once a week, rinse then apply a tiny bit of curl cream and some gel to soaking wet hair, still in the shower. When i get out, I remove excess water by scrunching gently with a sports towel.
Applying the products to soaking wet hair was an absolute game changer for me - it really does seem to trap the moisture into my hair and give amazing curls.
What i would say is you shouldn't need much - it doesn't have to be complicated so you can get away with a 99p alberto balsam conditioner from home bargains and a gel like one from asiam, boucleme or the blue LA Looks gel from amazon which is good value.
Personally, I find the CurlFlo products to be amazing and have now switched from Boucleme. They smell fabulous and i get zero build up on my hair with them, even after a week my hair still feels light and fresh.
Good luck!
