Hair regrowth

Tips on getting this to grow back. I pulled my hair back in this towel after my shower so I could get a better picture along with the baby hairs. I'm so self-conscious of it. It's on both sides, and I can't even wear my hair back because it's so noticeable. I'm not a big believer in pills that say they 'help'. I feel like they are a scam and are so expensive. I plan to start taking my prenatal again as I heard that helps with hair and nail regrowth.
