If you've tried Reverse Washing and it didn't work for you, or if you've been thinking about it but perhaps are afraid that it's going to leave your hair a dry, brittle, tangly mess, here are the best tips that I can give you based on my own personal experiences:
1) Make sure that you hair is fully saturated with water before you apply your conditioner. If you hair isn't totally soaked with water, it's going to be difficult for you to distribute your conditioner throughout your hair from root to tip. Trust me on that one.
2) After you apply your conditioner, leave it in for the regular amount of time that you would normally use. I like to apply my conditioner, then go about my business (shaving my legs, etc.) before I use my shampoo. This is exactly how I do it when I use shampoo first, followed by conditioner, so nothing changes in terms of the amount of time spent in the shower.
3) When it's time to rinse, DON'T RINSE. This is the fatal error that many first-timers make. If you rinse your conditioner out and THEN apply shampoo, you're very likely going to end up with dry, brittle, tangled hair. Use your shampoo to remove your conditioner. Here's what I do: after my conditioner has been in my hair for several minutes, I quickly tilt my head in and out of the stream of my shower and get it a tiny bit more wet. Then, I apply my shampoo. I use about 25% less shampoo than I would use if I wasn't doing a Reverse Wash, because I don't want to strip my hair of all the conditioner. After I apply my shampoo, I lather and rinse as usual and...that's it!
