Actually repaired my hair

I was honestly skeptical because every “repair” product usually just coats your hair and makes it feel soft for a day but this product is different. For reference, I have dry, heat-styled hair and after about 3–4 uses, I noticed a real difference in how my hair behaves. I have less frizz, smoother ends, and it feels stronger when I brush it. It’s also way more manageable and holds a style better.
