The primary ingredients for a natural looking curl on relaxed hair are:
conditioner
curl spray or gel and/or styling creme
serum
Some people may not need the styling creme and the curl spray togther. I can do without the styling creme in a pinch for instance - but not both.
The products I use to achieve my curl vary, but for the most part I use the following:
Any leave in or lightweight rinse out conditoner will do. Lately, I've had fab results with Sebastian Moisture Base. Again, any conditioner that you like that isn't too heavy and doesn't have too many cones will work. I wouldn't go for instance with a cholesterol conditioner.
I religiously use and will never give up John Freida Dream Curls. That's the curl spray that does the trick on my hair. A good gel that has a similar purpose is KMS curling balm. Either will effect the same results - to encourage and hold the curl in the hair minus crunch (a determining factor for me). If you have a hard time with the sprays and gels some people's hair responds better to non-alcohol mousse. John Frieda's Frizz Ease line has one that is superior.
Point? You need something to encourage the curl.
The styling cremes (I like Salon Selectives Loosely Defined and my favorite is L'oreal UnFrizz Taming Creme) are optional but they give a nice finished look and some control if your hair tends to get too big as it dries.
The serum is key. I've experimented a lot and you need a good thick one. I like Keracare's Silken Seal. It should go after the conditioner and the creme's but before the spray. The product encouraging the curl should be the last to go on.
The rest is in the technique. I lightly wrap a towel around my head after washing just so it's not soaking wet. A minute or two - tops. Then I apply a tablespoon size of conditioner (mostly to the last 3 inches of my hair) and the styling creme if I'm using one. Then I tie my edges with a satiny rectangular shaped scarf (I mention the shape only because it should extend back toward the crown only about 2-3 inches - otherwise the top of the hair will be flat). I leave the scarf on until it's mostly dry and to the the area that's left free I apply the curl spray liberally and then the serum.
Then I DO NOT TOUCH IT, DO NOT TOUCH IT, DO NOT TOUCH IT (can you tell this is important?
) until it's 75% dry. It should feel slightly damp but mostly dry to the touch. At that point I lightly gather just the tips of my hair in my fists and squeeze gently. That helps encourage the curl on the strands that aren't going with the flow. It helps to bend over and let gravity help spearate the strands from one another to give a nice, full appearance.
Class dismissed.
