Colour B4 review and how to get rid of the smell? So i made the school girl error of dying my hair a semi permanent dark brown color last November. I loved it at the time but then began to miss my natural blonde/brown hair. My mum was watching TV and saw a Colour B4 advert and recommended it to me. I decided to give it a try, i followed all the steps on the packaging and used the buffer provided. My hair color didn't change dramatically at all, i was the only person who could tell the difference. But what change drastically was the smell of my hair, Colour B4 stinks of, Veet hair removal cream and doesn't just disappear when you wash it. So now i just had really smelly hair, that actually made me gag it was that bad. I dyed my hair on a Saturday and had to get rid of the smell before going to school on Monday. I tried everything, first i covered my head in vinegar and the smell didn't ease at all. Then i tried washing powder and initially i thought it had done the job
