Following on from the previous post about what makes shampoos harsh, I am setting myself a challenge but I need your help.
My hypothesis: Most modern shampoos (not soap based) will fall in the weakly acidic to neutral range (pH 5-7). This hypothesis is based on the fact that the surfactants used in shampoos generally are slightly acidic and cosmetic chemists tend to pH skin and hair products to this range.
My challenge: To catalogue the pH of shampoos used by readers of The Natural Haven.
How: Create a list of the shampoos used by readers, request samples from the manufacturer for pH testing or request the pH value of the product from the manufacturer should they keep a record. Finally publish this list on the blog to see if the hypothesis is correct or not.
So here is what I need from you:
1. Please tell me the shampoos (brand and name) that you have used within the last 2 years.
2. If you found any of the shampoos to be harsh/irritating on your hair or scalp, please state so
Please exclude soap based shampoos (castile soap, black soap and shampoo bars) which are most likely alkaline.
I will go first
1. Herbal Essences (hello hydration, dazzling shine), Johnson and Johnson (baby shampoo)
2. Herbal Essences (Hello hydration)
Your turn and do spread the word!
