Make a combination of these products.
There's probably a solid 5 to 8 ingredients you could make your own serum, and yeah, I think you'd be better if you could leave it in there at least three times a week for an hour.
Good example of a product, minus the pharmaceuticals in it.
Definitely add the peptides!
I'm basically going to spend a couple of hundred bucks, looking for the highest quality ingredients and then I'm going to measure and create my own serum.
You can also add drops of the serum to any natural shampoo or conditioner you use!
