The scalp serum I’ve been using since having my first daughter. I had thick hair as a kid and was always afraid I’d lose it as I got older. I truly believe this serum has been what’s helped keep my hair healthy and some of the thickest I’ve seen from my age demographic at age 37. Stock up on Amazon Prime sales or website sales, it lasts a while if you use it modestly! LTKBeauty LTKOver40 LTKselfcare
