When I was in high school some of my blonde friends would put talcum powder in their hair to absorb oiliness between washes. When I tried it my dark hair looked like I was going grey!
Batiste Dry Shampoo uses a similar concept but has a range of options, including one for brunettes! They come in pretty aerosol cans and are beautifully scented.
They're fabulous to take on holiday or to use when life just gets too busy to give your hair the TLC it needs.
I use it to tie me over between washes or to just give my hair an extra bit of volume if it's flat or a bit lifeless.
So awesome to use if you are late for work and you notice last minute that your hair is just too oily for you to leave the house!
Warning though. I got into the habit of using it once a week. I think it has massively changed the production of oil on my scalp. I used to get away with washing my hair 1-2 a week. Now I need to wash it every second day. I have very coloured, curly, dry frizzy hair so my hair doesn't handle regular washing very well.
I regret ever using it, even though it was good while it lasted
