The Nature Made vitamins really didn't do anything for me. I found the dosage of biotin and other goodies to be lacking, especially compared to that Sugarbear stuff. So I tried some "high potency" hair, skin, and nail vitamins. After looking at the bottle, it is actually very close to the Sugarbear Hair... and then some. There are even more things packed in than I expected, which is good. What's even more good is the fact it is wayyy cheaper at $15 a bottle, and I got these buy 1 get 1 free.
For me the biggest telltale sign of this stuff working is your nails getting hard, and I'm talking use it has a flat head screwdriver hard. By the time these photos were taken, I had finished the previous stuff and have been on the new ones for about a week.
One of the lamest things is seeing yourself in the mirror, thinking "Wow, I look so different than before! There gotta be some delicious changes compared to the previous months." then coming here to compare photos... and get disappointed.
I am seeing lots of new baby hairs and the line where they all kind of stopped. It is crazy to see my hairline progress forward, but the hairs are still very small just barely visible in the photos. When I stand under a light I am seeing less and less of my scalp.
But man, am I ever going to come even close what I had in my teens? Who knows, but here is my progress so far.
