I had added 20 drops NPF to a 50/50 mix of Cure Care and water and was using that morning and evening to make sure my hair was getting enough conditioning/moisture in our desert climate. Yesterday, I emptied that bottle (12 oz. I think), so today I filled it with water and added 1 tsp of NPF. After thoroughly wetting my hair in the shower I sprayed this liberally on my hair, no gels, conditioners or other stylers at all, and today have the best curl ever. Apparently my hair is protein starved. I have been using regular PTs and noticed some curl improvement after each, and I have also been using a lot of products with protein in them, but this is the most dramatic improvement ever. Tomorrow I will see if this day can be repeated. My other good days were never reproducible.
Experimenting with too many products to name here. All this great info keeps my head spinning.
