No sorry I don’t have heat damaged ends. Sometimes my hair will get dry and I just made sure to keep it really moisturized with my leave-in Mixed Chicks conditioner and Mizani Moisture Stretch cream (when wearing it natural).
You may be putting too much heat to your hair which is causing the damaged ends. Consider getting your hair trimmed to get rid of the dead ends, and ask your stylist what products they recommend to protect your hair if you prefer wearing it straight. Hope that helped 🙂
