Texturizing in terms of thinning your hair with a razor is a definite no-no
•Protein can be good for your hair (some hair likes it like fine hair, some hair doesn't like coarse hair - most important thing is to know your hair properties: texture, porosity, and elasticity, and go from there - the site the above poster gave should help you figure those out) - also, if you can't figure out your properties, you can send your hair in to that site and have them determine your properties for you (it's what I did and it ended up being a great purchase)
•Some silicones are okay - there are a few articles on nc.com about silicones, including which ones to watch out for and which not to (for example, some silicones have the word "PEG" in front of them and are water soluble, so they're generally okay)
•Diffusers are great when it comes to using a blow dryer because it disperses the heat (instead of a straight shot of direct hot air, which could make your waves straight, it makes it so it's more gentle, so your waves can set up more - although some wavies do like air drying better)
•Layers are generally great - they make it so more waves are lighter (in terms of the hair weighing them down) and can spring up more easily
I know this is all a lot of information, so try not to overwhelm yourself...give yourself time to read and digest it...good luck
