Query: Why do you think sulfates are bad for your hair?
In the past, I'd see people saying that SLS or sodium lauryl sulfate was bad for our hair, and I wondered why. On a scale of 1 to 10, with a rating of 1 and 2 meaning your surfactant is gentle and a rating of 3 and 4 meaning your surfactant is mild, SLS is a 4.5 to 5 rating, which is still really low compared to the surfactants of the past. And you don't use a surfactant neat on your hair - there are so many ways to increase mildness in a surfactant based product, that just about any blend of foamy, lathery surfactants can be considered to be mild these days.
What about sodium laureth sulfate (SLeS) or ammonium laureth sulfate? What about sodium lauryl ether sulfate? What about alkyl glyceride sulfates? And what about behentrimonium methosulfate? Do you consider all the sulfates in any category of ingredient bad? Why?
A thought...Where did you get the idea that sulfates are drying? And that they are more drying than other foamy, lathery surfactants?
I really want to understand why this is coming up over and over again, so please share with me what you know about this concept and the reasons we aren't supposed to use sulfates on our hair as well as what the impact of using sulfates might be on your hair and scalp. What philosophy or website told you about this idea? What are you using instead of sulfates on your hair? I'd love to hear from you about this!
