Update :
I had a weird reaction to Propylene glycol. After I added it the formula it gave me estrogenic symptoms like anxiety and puffy
face and nipples. I could not find any studies on it being estrogenic , quite the contrary actually . There are some studies showing it might be progestogenic.
I have removed it anyways from the formula.
I have since then slightly increased ethanol to 35%, to make up for propylene and to increase polyphenols absorption, since they don't dissolve completely.
I also noticed that adding sugar makes my hair a little sticky. So I have created a new batch without the sugar as well, only containing NMN, apple polyphenols and ethanol. I can leave this formula in my hair and it looks good, not even a need to rinse it.
So it's very practical for every day life .
I think I'll make a separate batch including the sugar for maximum effects that I'll use when I don't have to leave the house.
I'm thinking about adding biotin to the formula for increased local glyocgen synthesis.
Current formula:
35% ethanol
1% NMN
1% Apple polyphenols
(1% of dextrose)
Rest: Water
add taurine ,caffeine,... to your liking
