I've always had some obsession with keeping my hair healthy and shiney, everything from baby oil and olive oil treatments to mayonnaise, raw egg, honey, even crude oil.
Yeah crude oil, with a rinse that smelled heavily of alcohol. Don't ask where I got the idea 'cause I won't tell. But, one day about 15 years ago I had just put the crude in, waited the time it said and was applying the alcohol stuff when my husband called me, saying "hurry up, get out here, Zenna broke out. She's running down the driveway." Zenna was a pony someone gave us free (she was rather old) but we loved her.
Without thinking I threw a towel over my head, ran out and got in the car. Geez, it took a few seconds to feel my head freezing in the cold hair. It was also quite stiff, sticking out every which way. But, I was determined to stay in the car, let him run after that pony. Nobody found the pony and my head was frozen. Well, the end of the story was everyone in town was looking for the pony. We gave her, free, to the family who found her grazing in their yard.
Well, I am way off course here. Back to the crude oil. Yeah, it did work, so I used it a couple more times. That's enough for one lifetime.
Now I use Nioxin products which work wonders for fine hair. I used to have thick, fine hair but now have brown and white thinner hair. Couldn't live without the mousse. We look around, find it on sale in beauty shops. I paid $10 for the whole set, gigantic bottles of shampoo, conditioner and mousse. Lasted 1 1/2 years.
Osso, I can see where that would work, rinsing out conditioner with vinegar, other things suggested too. Will try them myself.
