Hi everyone! I started using a shampoo bar and noticed that it was leaving a sticky oily residue in my hair. I've read that there is a "transition" period were your hair tends to be nasty for awhile until it gets use to the new shampoo and I guess strips the product of the commercial brand shampoo and conditioner, but I don't know if I'm going through that "transition" period or that I have hard water. The reason why I'm unsure is because when I wash my hair with the shampoo bar my scalp and bangs are clean and soft but the length of my hair (ears down to hip length) feels sticky and oily. I have used an acv rinse and my hair was feeling less sticky but still oily. Also before I used a shampoo bar I would only shampoo my scalp with the commercial brand shampoo and then only use conditioner and oils or other conditioning products on the length of hair.... I'm wondering if I should have washed my hair with a regular shampoo to strip all the product out of it before I had used the shampoo bar. Does anyone have an idea to what's going on? I'd love to hear all your experiences if you used a shampoo bar or maybe experiences you've heard others go through. Also is there a way to test for hard water? How do you find out if you have it?
