Up to 10″ virgin thick wavy red hair with natural blonde highlights

Virgin, thick, and wavy natural red hair. I wash 2x per week with Nexxus products and only air dry. Hair has been styled with heat 5 times since grown out to this length. I live a healthy and active lifestyle (marathon runner, have a nutritionist) and don’t smoke. I mostly wear my hair naturally wavy with mousse as the only product, or in braids. I’ve never had my hair colored or treated in any way. My hair does get slightly frizzy in humidity but mostly just feels heavy. My hair has natural blonde, light red and dark auburn red highlights. The darker red hair strands are thick and coarse while the rest are thinner and soft. I have longer layers (about 2-3 inches shorter). Willing to cut up to 10 inches!
