I have been meaning to research up a bit on palmitoyl tetrapeptide-20, which in many in-vivo studies helps melanin production in the follicle, which can transfer via the hairs' natural transportation systems to the roots. (given that the hair is in good condition and is not damaged — by heat or drying products)
This is very groundbreaking for my mid-40 year-old mother
I wanted to find a nice treatment spray that contains this peptide, but the most famous one (Phyto) contains a lot of alcohol and would likely weaken hydration levels. She hates brittle/dry hair . . . so not the Phyto.
I contacted some cosmetic suppliers and requested for samples of palmitoyl tetrapeptide-20. I want to make a simple spray for my mother, with: water
hydrolyzed silk (7%)
black walnut hull extract (5%)
purple tulip extract (3%)
PhytoCell Argan (3%)
palmitoyl tetrapeptide-20 (Greyverse) (1%)
HOW MUCH OF THE PEPTIDE SHOULD BE USED?!
Are there any penetration enhancers that can be used to enhance the results of this spray? Anything I should be aware of?
Thank you in advance!
