For many of us dry shampoo is a time saving product, handy for refreshing your hair in between washes and adding some life to your roots but Belfast lady Nicole Baxter took to Facebook to share her horrific experience with the product.

Her nightmare began when she noticed a bald patch on her head and decided to go and get it checked by a doctor as she didn’t see an obvious reason for her hair loss.

“So I went to my GP at the end of last year due to having a bald patch on my head which kept getting bigger. 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.”

After being referred to a dermatologist she was told she had triangular alopecia and would need a biopsy.

In preparation Nicole stopped using the product and when she attended her appointment the doctor noticed a huge change and cancelled her biopsy.

“She compared my scalp today to the pictures that were in my file from February and asked what I had 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.”

“I left the hospital with my scalp fully intact and a prescription for a bottle of T-Gel!”

Nicole concludes her post with a warning to people who use dry shampoo frequently:  “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.”
