For the last few years there has been a huge wave of people going "sulfate-free" in their hair care regime. Sulfate free shampoos, sometimes dubbed cleansing conditioners, tend to be pricey ( WEN) and are harder to come buy than your regular old shampoo (although there seems to be more and more poping up on grocery store shelves- (Hello! L'oreal!). Many have went to the co-method of washing their hair. The co-method, or conditioner only method, also know as the no-poo method or CG (curly girl) method has tons of loyal followers who swear their hair has never been better, but really is it for you?
The co-method is quite simple, buy a cheapy conditioner , one that has a runnier texture and few to no silicones and little heavy conditioning agents (Suave, White rain and Vo5 seem to be the hands down favorites and Suave coconut conditoner seems to have a cult following) slather a large handful or two on, massage it in your hair and scalp, let it sit for a few minutes and then rinse. You can follow up with a heavier regular conditioner if need be.
Generally, this method was used by those with kinky, curly, coarse and/ or parched hair and dry scalps but it seems like everyone has hopped on the bandwagon, including myself. However, in the end ,co-washing does not seem to work for me.
I am an everyday shampooer, have always been and probaby always will be. I am on a never ending journey to have super long hair and figured co- washing would force me to shampoo less (which supposedly is better for hair but for me the jury is out on that one) and therefore leave my hair and scalp healthier, in theory.
I have used both Vo5 kiwi and lime clarifying conditioner and vo5 strawberries and cream conditioner as "shampoo". I will say that these are very easy to spread and massage into hair, although you need much more conditioner than shampoo to feel like your hair is actually washed. They rinse very easily and both smell great.
I was pleased with my hair on the first day, there really wasn't much difference than when I use real shampoo except my hair felt thicker. Day two- my hair was nice but my scalp didn't really feel clean and by the end of the day my head was a little itchy. Day three- forget it, had to shampoo. I have tried co-washing a few times in the past few years, shampooing on the third day, shampooing on the second day, shampooing every other day but in the end I go back to my daily shampoo. I have long thinner hair that has a slight wave, my roots are oily and the length is dry/damaged. I had high hopes for co-washing but my scalp and hair and me, for now, are much happier with a daily shampoo, daily conditioner and a daily leave in.
I can see why co-washing can be benefical for some, many shampooos do contain harsh sulfates (sodium lauryl sulfate is the big one to avoid) which can cause scalp irratation and dryness. Co- washing is gentler on the hair and scalp and for those who only shampoo a few times a week co- washing can help stretch your shampooing while leaving your hair still feeling clean for the most part.
However, ONLY using conditioner on your scalp can cause build up, eventually leaving hair greasy and lank and causing scalp itch. For those with thinner straight hair the effect may be felt sooner than others. I donot see how you can go completely shampoo free, your scalp and hair still need a cleaning. For some maybe a weekly or monthy shampooing may be all they need to still have co-washing work. I have also read posts wear some just do a baking soda wash (dissolve baking soda in warm water and use it just like a shampoo) or vinegar rinse to rid their scalp and hair of buildup.
If your curious about co-washing- go for it, it won't hurt your hair in any way shape or form and if worse come to worse you can always shampoo.
