I purchased my krachai from an Asain grocery store in here in Florida.  I posted a picture of the root in a prior post.  It has long fingers:

 

Bhavani: 

I grind it in a blender with water and put it in a pitcher and drink 3-6 glasses per day (the entire pitcher).  I would drink gallons of it I knew it would work!

My root looks different than the one you posted.  It has long fingers.  There was a ginger root that looked like the one you posted but I thought the one with “longer fingers” was the correct one according to Bao Saka.  My root also does not have that deep purple color to it like the one you posted.  Maybe that is why I haven’t seen any results?  Surely there are other members trying the experiment?  Anyone who has been getting any results, please share.  I have seen no change and I think it’s been 6 weeks or so.

Well, I’m sure the cure for hair repigmentation will be discovered by a major cosmetic company like L’Oreal someday.  I do hope it is soon.  I also hope that if someone finds a reliable way to reverse gray hair on this forum, they will share.  Getting excited for rip-off products like Melancor NH and Recoleur has made me a skeptic.  Though I should mention both products have not been endorsed by the FDA to cure gray hair.  I knew this before purchasing these products but assumed the FDA is just another slow, federal, American agency that takes its time with new products and is close-minded when it comes to alternative herbs/roots/medicines.  I’m sure who ever does find this miracle cure, it will be backed by the FDA.  I started to get gray in my late teens, and unlike some people who come to love their gray hair, I absolutely hate mine. I have fair skin and somewhat of a baby-face and it makes me unhealthy or sick.  I am 30 yrs old and it just doesn’t fit me and I would love to find a cure!  So if anyone has any luck with this “bimatoprost” please share.

 

Bimatoprost is a derivative of the prostamide F_2α, which is enzymatically formed from PGF_2α and should act similar like PGF_2α, but has a lower receptor affinity.

 

 

supposed to be replaced by a new cell via the stem cells, is not replaced.

(Presumably due to lack of enough healthy living stem cells) No melanocyte = no melanin.  So the fact is that the cells do get worn out, and die just like evey other cell in the body.

 

The process of producing melanin is an oxidative one.  So antioxidants can certainly help delay the aging of the cell.  And, of course, supplying enough raw materials for the melanin forming reaction can help the cell's melanin production be more efficient.  But simply stimulating the melanocytes to produce more melanin, does not keep the cells young and healthy.  In fact, it likely does the opposite.

 

So say, for instance, that ingesting or topically applying a tyrosine compound

stimulates increased melanin synthesis.  More synthesis = more oxidation = more

wearing out of the cells.  So while you may see a hair getting darker in the short term, you are sending the melanocyte to a quicker death via upregulation of an oxidative pathway.

 

If you simultaneously increase antioxidants (orally, topically, whatever), and protect the cells from UV radiation (sunscreen in the shampoo, PABA, etc) and other toxins, you might come out equal.  But eventually oxidation will win and the melanocyte will die.

 

So the key is get the body to produce more of the STEM CELLS.  Then the dying melanocytes can always be replaced.  Couple that with the proper nutrition needed to supply the raw materials for synthesis, and your hair would stay non-gray forever.

 

When you are young you have plenty of stem cells alive to supply new

melanocytes.  Perhaps someday you will have your own stem cells extracted, multiplied, and injected back into you as a re-youthing method.

 

Or some wise person will figure out the set of circumstances that causes the body to produce these stem cells and duplicate it to stimulate the body to produce them on demand.

 

Until then I doubt any chemical, herb, vitamin, etc will have more than a delaying effect on gray hair.  This delaying effect may be enough to appear as a full reversal, since hair grows in cycles, and is likely fed by multiple sets of melanocytes.  The difference being that a real full reversal would restore the system to the state where the hair would continue to appear as normal color well after treatment with any nutrients, etc was stopped.
