Reducing Toxins: Natural Hair Rinse

I've been using a shampoo bar by Tammy Sue for a few years.  Just recently I've been using the below concoction as a hair rinse and I really like it.

It is NOT a conditioner but it does detangle my hair and seems to make it softer and smoother than when I am not using it.  Most conditioners leave my hair feeling heavy and with an oily scalp.  This one fits my hair and scalp just right.

The Recipe
1 tablespoon (or so) raw apple cider vinegar and 15 oz water.  After shampooing, I squeeze it onto my hair then rinse.  This bottle lasts me 7-8 washes.

Anyone else use this?
