I have posted before about co-washing, and have debated whether it really worked for me.
After two years of off and on and several months of serious trial I believe co washing is the way to go. Fact is I have been co-washing faithfully for 4 months now (with an occasional shampoo to clarify) and when I recently tried to go back to a traditional shampoo and then condition my hair was awful.
There any many, many post on co-washing on "curly- girl" and ethnic hair care sites but I have found that many of those recommended conditioners do not work well for straighter, less dry hair and scalp types.
I have found the key to a good cowash conditioner is one that has little to no silicones or heavy conditioning agents. Avoid ones with any silicones high on the ingredient list and avoid dimethicone completely, as it tends to the the "strongest" silicone and can cause buildup quicker, requiring some form of surfactant to remove. Silicones aren't bad but if you want to co -wash a conditioner with alot of silicones will not leave your hair feeling clean. It will be greasy and heavy feeling.
Look for conditoners that contain one or more the following :
cetrimonium chloride
stearyalkonium chloride
stearamidopropyl dimethylamine
dicetyldimonium chloride
behentrimonium methosulfate
These are what cleanses your hair .
Go cheap!! Really, hit the dollar store. Some of the no name $1.00 conditioners are great options for co -washing.
If you want a bit more moisture in your cleansing conditioner look for ones that have glycerin or even oils lower on the ingredient list. Oils are what I consider a natural alternative to silicones.
After testing lots of conditoners (All the vo5's, White Rain and Suave Naturals plus a handful of no name brands) here is what I have found from my experience.
The best conditioners for co- washing are-
Suave Daily Clarifying conditioner- best overall performance period.
Suave Everlasting Sunshine conditioner - best scent. Most of the Suave naturals have almost identical ingredients just different scents so if you prefer a different scent go for it. However, I say avoid the insanely popular Suave Coconut it contains ammonium xylenesulfonate which can dry out hair.
Silkience spa haus salon conditoner- only sold at Dollar Tree- best for moisturizing without being heavy
Vo5 and White rain are also really popular, but didn't make my best of list simply because I really think these others out perform them. I did review Vo5 conditioners in the past but again I feel the ones listed above are better. However, I will give Vo5 Chamomile Tea Therapy honorable mention. White Rain is good, its just getting harder to find.
I tend to alternate my conditioners, mostly out of bordom and the fact that I am a product junkie and like to try new things. Then once every two weeks or so I shampoo with a non conditioning shampoo- such as Suave Daily Clarifying or even a cheap generic baby shampoo. ( I prefer shampoos that only contain sodium laureth sulfate- not LAURYL its to strong) My hair has never felt softer or been more manageable. Now if it would just grow super long, but thats another story.
