Maybe i'm just imagining it, but I feel like these have been helping my hair a lot. It seems a lot shinier and silkier. I love that that these are in capsules instead of tablets, so I can just open the capsules instead of crushing them. I mainly bought these for skin health, (I take them orally, as well as occasionally mixing them in with my moisturizer, as pantothenic acid speeds wounds healing and improves skin texture and elasticity) I highly recommend these. I've bought a few different brands of pantothenic acid and usually the 500mg only account for 5000% DV but these count for %7250 DV, so these are more potent than other brands!!! Jarrow is an awesome brand too, I highly recommend this if you are shopping around for pantothenic acid!
