Welcome! I too am new, so I won't be able to offer as much advice as many of the vets here, but I can try to let ya in on what I know.
I to have wavy hair that I have been wearing straight for about 3 years. I noticed that it had become very dry and unhealthy, so I decided to go 'au-naturall'. I have been very happy with the results so far!
I am attempting the no poo method, so I am not shampooing at all. I am strictly a co-wash girl! You can check out my signature for the specific products, but I can tell you that I am LOVIN the JessiCurl products! I too was having frizz problems and as my hair is so think, I could never get anything to give me lasting hold! The JC Rockin Ringlets
and Confident Coils
with the Biosilk Rock Hard Gell are my faves right now! It makes for great curls and clumps, with little to no frizz, and I get great volume! I am a morning hair-doer, so I also keep the JC Gelebration
Spray in my purse for touch-ups, and it is working great.
Another tip that works for me is the almighty scrunch! I live and die by the scrunch..well my hair style does anyway! If my scrunch is not right, then I can't get my hair to look right! I never use towels on my hair, only Curlease or t-shirts...and I scrunch to my hearts content, althought my magic number is 10! I scrunch eveything 10 times, by section, and it works great!
Remember that not every product works the same on every curly. What works for you might not work for someone else, so it is all trial and error! Just start out simple and then work your way up... HTH!
