Collagen🤔

I’m just curious as to anyone else who’s used collagen supplements. I’m 21, & I know I’m young & still have youthful skin but I’m more wondering about the benefits for hair growth & whatnot.

When I get extremely stressed out my hair thins out. Back in middle school I had bald spots all over my head because of stress.

I’m wondering if taking a collagen powder supplement would help in a way. I know y’all aren’t doctors lol I just want to hear other people’s experiences with collagen supplements or collagen products that aren’t skin related. (If it helps with my acne than that’s def a plus but its not needed)

Please & thank you ❤️✨

Also any brand recommendations would be nice (currently looking at Physicians Choice)
