Dry shampoo is a life-saver for many, but for Nicole Baxter it turned into a nightmare. The Belfast lady took to Facebook today to share her dry shampoo horror story, in a bid to warn others to watch out for signs of intolerance. Nicole went to the doctor when she noticed a small bald patch on her scalp and had some blisters and pain. She wrote: 'Anyone who knows me knows I don't stress and my diet's alright so there didn't seem any reason for this to happen? 'My scalp was also very itchy and flaky. I had wee red sores and blisters all over my scalp and a terrible burning sensation all over my head- to the point where I would wake up several times a night due to the discomfort/pain.' She was referred to a dermatologist who diagnosed her with triangular alopecia and told her she would need to return for a scalp biopsy - a painful and invasive procedure. She continues: 'She advised when I come back for the scalp biopsy to come with nothing in my hair and to make sure it was clean. 'I thought it was weird she said that, it's only dry shampoo, what's that got to do with it? So I actually stopped using it all together from that day to see what would happen.' However, when Nicole returned this week, a new doctor noticed a huge difference: 'She compared my scalp today to the pictures that were in my file from February and asked what had I done differently in the last 6-7 weeks that may have helped it. 'I told her I'd stopped using dry shampoo and that was it, nothing else different. 'She said it's the best thing I could have done for myself.' Nicole concludes: 'Moral of the story- Dry shampoo caused me to now have this bald patch on my head (which I still have and it may or may not grow back, but nothing can be done) and a terrible scalp for ages. Just wash your hair people! It is not worth having this awful patch that I might be stuck with on the side of my head all because I can't be arsed to dry my hair.'
