Not sure if this product line is for me. I have very fine hair but its a stage before ringlet curls and this doesnt enrich them and no matter how little I use it seems to weigh my hair down and make it look greasy. I have been a professional licensed cosmetologist for 39 years and have used hundreds of products. I spent $200 so I need to keep using the shampoo and conditioner but not sure of the 4-6 styling products I purchased. I feel a bit disappointed.

Light Serum Fights Frizziness and Dryness

The front part of my hair is very dry and high porosity. In the past I have relied on heavier primers and leave ins because I end up with very frizzy hair that stands on end in front if I use a lighter leave in . (No really...the hair on the back looks like it belongs on a different head.) This is a very nice serum. I completely coats the hair and gives it a decent slip without being heavy. I didn't end up using a lot either and considering its cost, that's a good thing. I use this and followed it up with the Good behavior primer

and a light cult gel and its banished the frizz for 2 days so far, even though I don't do much more than re-wet my curls in the morning so I don't look like Medusa.
