Below is a video to show darkening of gray hair with 100% Natural Hairgrow Serum.
What is it? Natural Hairgrow Serum, a Rejuvenating topical treatment, promotes hair regrowth and an interesting side-effect is that it helps regain natural hair color to hair gone grey.
Hair darkening to original color is a progression and will take some time- Grey hair, turns a darker grey in a few uses until it gets back original color. Effectively used for Blonde, Redhead & Black hair.
Use 1-2 times weekly. Recommended to use for about 2-3 months for most cases, after which maintenance of 2-3 times a month may be necessary. It is subjective.
1. Hair should be dye-free for 1-2 weeks or more- until it is at natural color
Synthetic Hair Dyes bond to hair & hence use of our Serum may not show benefits when using along with dye.
If it is too drastic, it is possible to apply Serum as grey roots grow out- use everyday or even twice a day for a few days to roots, cover with cap, bandana, etc.
As rest of any old dye fades out of hair Serum can be used to gradually replenish color.
Please see that most dyes like Black Henna , etc are synthetic, not natural dyes. Always check ingredient list.
Use of Natural Hairgrow Serum does not make roots come out dark, only the hair it is applied to becomes dark , healthy & more vital.
