Before I buy any hair serum, I always check a few things. I look at my hair type first, because what works for my thick, frizzy hair may not work the same way for fine or oily hair. I also pay attention to the ingredients, the texture of the serum, and whether it leaves a greasy finish. For me, a good serum should make my hair look healthier without making it feel sticky.

When I use Trader Joe’s Hair Serum, I apply a small amount to my palms, rub it together, and smooth it through the mid-lengths and ends of my hair.
