Although palmitoyl tetrapeptide-20 shows scientific potential, there are some conditions and limitations to keep in mind when actually using it:
Not effective on completely white hair:
Palmitoyl tetrapeptide-20 mainly works on gray hair (hair with some active melanocyte cells still in the follicle). If the hair has turned completely white and there are no active pigment cells left in the follicle, this ingredient won't be able to work.
Not a medical drug:
Currently, the medical community generally agrees that there is no definite cure for premature white hair. Palmitoyl Tetrapeptide-20 is mostly considered a cosmetic active ingredient that may help slow the graying process or improve early gray hair.
Multi-factor management:
The appearance of white hair is influenced by many factors like genetics, stress, nutrition (such as vitamin B12 deficiency), and thyroid issues. Besides using related hair care products, reducing stress and improving nutrition are also important ways to help slow down graying.
