Cetirizine to Block PGD2?
Hi Doctor,
Some people started to use topical cetirizine to block PGD-2, they all say that they have re-growth from it and thickening up the vellus hairs and make them vellus in 3 months or so? it might be true?
I really do not know the answer. There is an association between cetirizine and prostaglandin D2 (PGD2), which is related to hair loss. There is no clear evidence that cetirizine, an antihistamine, can restore hair at this time. Just applying it to the skin makes no sense to me.
Do not take cetirizine orally! cetirizine drugs are under a drug watch which the FDA has lanuched in 2012.
Why not? i’m using a half tablet (5mg) everyday because i’ve allergies. What is dangerous about it?
Typical, the FDA are o.k with o.k ing dangerous drugs like propecia but the minute something as harmless as ceterezine starts working for mpb its “dangerous”. Its been used for years for allergies !
