Lush still use it in their shampoo bars.
The more I hear about Lush, the more I am convinced their formulators have no idea what they're doing.
I was going to start ranting, but I think I'll just leave it at that, lol.
My daughter is in her 30's now, and we formulate most of her skin care products. Yes, her dermatologist gave me a list of very long names for the related ingredients. I found a lot of them in the soaps and shampoos we used. I make my own laundry soap mix, because a bunch of those have the same junk in them. We have had to un-junk our lives, because my Granddaughter has the same sensitivities as her Aunt. 2 out of the 5 in my family are allergic. I am developing a few allergies myself, but to medical ingredients!
Did the dermatologist say that she just develops allergies easily? Some people do. If that's the case, then I would have a chat with her dermatologist and see if there are any surfactants she isn't likely to develop an allergy to, or strategies for preventing allergies developing (like rotating products). After that, if you want, maybe I could help you come up with a product formula she can use as a shampoo.
If the doctor recommends she not use any synthetic surfactants at all, then I guess she's stuck having to use soap on her hair. Soap is great as a body wash though so she will want to keep using it for that even if we figure out a shampoo for her.
And I wouldn't call ingredients "junk" just because a family member is allergic. Some people's immune systems malfunction sometimes, that's all. Usually, there is nothing wrong with the ingredient itself. When I had my environmental allergy testing done, I tested either severely or moderately allergic to literally
everything on the test, with the sole exception of horses. It was a pretty comprehensive test, too, and included every local pollen, mold, animals, etc.. So I know about allergies. I totally feel for your family and I'm sorry you have to go through that.
Soap is not good for the hair. The pH from soap is around 7.0, however, the pH of hair is around 4.5 to 5.5. This is why people use an apple cider vinegar rinse afterwards to help lower the pH of the soap. Using soap as shampoo can ultimately damage the hair down the road.
The minimum pH of soap is 9. If you get much lower than that, it stops being soap. Paper pH test strips don't work for soap and will always show a lower pH than what it actually is.
OK, so when? 4 years later my hair is much thicker and quiet nice. No more excess dandruff and the greasiness is gone.
Those are effects on your scalp, not the hair shaft itself. What we're discussing is damage to the hair shaft. Your scalp is skin, and almost no one disputes that soap is good for skin. And like I said in a previous post, if you need a shampoo that removes very little of the natural oil, you can do that with a syndet bar. You can probably make it remove even less oil than soap does. Removing too much oil when you wash is what triggers your scalp to start producing more oil than what's really needed, making your hair greasy and wreaking all kinds of havoc.
