@Chicoro -- I don't know how to multi-reply so to answer your other inquiry.
@IDareT'sHair - I think a good growth and strengthening combo is Amla, Methi (fenugreek), Brahmi, Neem & Maka (Bhringraj).
I haven't had any buildup when I was on the shea butter because my hair stay moisturized so there was no issues there. I didn't have to apply it often throughout the week, so no issues with buildup. Also, you don't need that much because a little really does go a long way.
The double boiler method for me worked and my butters still came out fluffy and whipped. I guess because I let the butters harden in the fridge. The only reason why I did the DB method was for the purposes of mixing those powders.
I took a picture of the final result so that you could see the color and texture of the mixture. I should have taken a picture of the butters when they melted down, but I started cooking at 4:00 am so that is when I made my butters because I knew the process would be long. I didn't think to take pictures while I was making it. Hell, I was cleaning collard greens.....I will say that when I used the wooden skewers to stir the powder and the butters and oils, I looked at this as a infusion method because the mixture was warm, so it's infusing. When I put it in the refrigerator, it's still infusing. There is no grainy feel at all. Just pure goodness! My powders were purchased at an Indian grocery store here in Virginia. Norfolk, VA to be exact.
I will use this mixture in between my tracks and on my edges, although I never had an issue with my edges.
The Shea butter mix can be used in so many different ways instead of a leave in conditioner. For example, I would use the mixture as a deep conditioner by adding on of your favorite conditioner to a small amount of your shea mix, concentrating on your scalp, edges and ends. When you rinse your hair, it should be very moisturized, this way, you won't have to use too much when you style your hair.
