So far i've done a the mayo twice, i've been reading about both on the web. You apply the mayo (enriched with oil,vinegar and egg, read to only use real mayo not salad dressing etc.) And avocado on dry hair before washing, leave-in for 30 minutes or so (use plastic cap)then wash and condition as normal. Can't wait to try the avocado...says to use really ripe fruit with or without EVOO. Least their no chemicals involved . Also have heard that the mayo has been known for hair growth as well. Wore braids for so long my hair seems so dry, can't seem to hydrate it. Just thought i'd share......Anna
