What I Looked for Before Buying
Before I picked a shampoo, I checked the ingredient list carefully. I wanted a formula that focused on onion and rosemary without being packed with harsh chemicals. I also looked for shampoos that were suitable for my hair type, whether it was dry, oily, frizzy, or thinning. A good scent mattered too, since onion-based products can sometimes have a strong smell.
