How to Change White Hair to Black
                     Can White Hair Turn Into Black Again?
The horror  you experience when your  first  white  hair  develops makes
white hair one of the most worrying side effects of modern existence. You
look for treatments and remedies to avoid spreading further since you
know there will  be plenty  more.  Hair  aging is  a  natural  component  of
growing  older.  Millions  of  hair  follicles  on  your  skin  contain  melanin
pigment. Gray hair results from pigment loss by hair follicles with aging.
 Can White Hair Turn Into Black Again?
First, let us dig deeper.
The development of  new cells causes the hair  follicles to lose the old
cells, which results in new hair growth.
There Are Three Phases.
• Anagen (growth)
• Catagen (cease)
• Telogen (rest)
Your hair reaches the end of its lifespan during the period of rest, replaced by a 
new strand.
The  innermost  part  of  the  hair  is  white.  Your  hair  has  a  genetically
determined color, given by melanin. Melanin-producing cells are found in
hair follicles, where they join with the keratin protein to form pigments.
Loss  of  melanin,  a  pigment-producing  component  that  creates
melanocyte cells, causes your hair to become grey or white. Your natural
hair  and skin color  are made up of this component.  Lighter  hair  color
indicates less melanin. White hair has no melanin, whereas grey hair has
very little.
It’s normal  to lose melanin  in  your  hair  as  you get  older.  In  fact,  the
chances that your hair will get grey are assumed to rise by up to 20%
every  ten  years  after  you  turn  thirty.  Due  to  health  conditions  and
heredity,  some  people  begin  to  show  signs  of  greying  earlier.
If genetics is the cause of your white hair, there is no way of reversing
them. But, nutrient deficiency can help prevent the premature greying of
hair.
People would wish to ask why is my white hair turning dark again instead
of how to turn white hair into black. Let us not turn wishful and focus on
our diet and hereditary information.
How To Prevent Grey Hair?
You should reduce stress since stress hormones might cause the hair
follicles to stop producing melanin. Practicing meditation and yoga can
help release stress for a healthy life.
• Although it can be difficult to stop smoking, a doctor can suggest
solutions that will  help you keep your weight off.  Smokers are at
high risk of pigment loss.
• Less exposure to toxins and pollutants
• Protect  your  hair  from the sun.  The harmful  UV rays can trigger
oxidative stress, leading to premature graying.
Conclusion
There is no way to stop hair from greying due to genetics or aging. But,
with a balanced diet and proper hair care habits, greying can slow down,
triggered by food, pollution, bleaching, and stress. Consulting with your
doctor can help you learn about your hair type to determine the best hair
care. It is important to have a nutrient-rich diet to enjoy lush black hair for
a long time.
