Renée, Brooklyn

Six months after my daughter was born, my ponytail felt like half of what it was. Nobody warns you about that part.

I didn't want a 'postpartum fix.' I wanted my Tuesday hair back. The density chart read like it was written by someone who'd been there.

A ReadyGo body wave in natural density. It moves like the hair I remember, and it goes on in under a minute — which is all the time a newborn gives you.

Weekdays it's the school-run piece. I keep the lace toned a half-shade warm and nobody has ever asked.

Start with natural density, not full. You can always add volume; you can't subtract a silhouette that isn't you.
