Just a comment about women’s eyebrows:
Women don’t usually shave their brows, Abe. They tweeze them. While shaving cuts the hair at the surface, tweezing pulls it out by the root, and that can damage follicles.
You’ll also find that women lose a lot of hair after menopause. Body hair, including eyebrow hair, becomes thinner and more sparse.
I shaved in November- but I can’t recall which year.
Whatever works…
FYI, EVERYONE… THE SHAVING INDUSTRY, IS DRIVEN BY ITS PRODUCTS, WHICH ARE IN TURN MANUFACTURED TO CREATE MORE BUSINESS. SHAVING CREME, IS DESIGNED TO STIMULATE FASTER HAIR GROWTH, LIKE “ROGAINE”, BECAUSE IF YOU STOP IT FROM GROWING, DO YOU NEED SHAVING CREMEM AND BLADES ALL THAT OFTEN? HMMM
ALSO MOST PRODUCTS MADE IN THE U.S., ARE DESIGNED TO NOT WORK 100%, BECUASE IF THEY DID, IT WOULD CREATE NO REPEAT BUSINESS… WORKING IN A POSITION LIKE THE ONE I USED TO, I LEARNED THAT MOST OF WHAT GOES ON IN OUR COUNTRY IS A SCAM AGAINST THE CITIZEN, AND SINCE BIG BUSINESS PAYS MORE TAXES, THE GOV’T SIDES WITH THEM.

Funny. I switched to shaving soap about five years ago (Caswell-Massey, for the record), and haven’t noticed any change in the way my beard grows. I haven’t actually gone to the length of switching over to the Sheffield straight razor, though. I’m afraid of it.
