Cut It More Often
"The ends of long hair have been styled and colored so many times that they get dry and frizzy quickly," says hairstylist Serge Normant. Ask your stylist to snip less than a half inch every other month (since your hair grows faster than that, you won't lose any real length). If you wait too much longer between cuts, split ends could resplit, which means you'll have to trim away more later on.

Dry Shampoo & Dry Conditioner
Sorry, but "when you've got a ton of hair, a big knot isn't proportional to your face," says Garren. "The ideal spot for a bun or chignon is at the nape of your neck—anything in between there and the crown looks matronly."
Give It a Boost
Long hair is heavy. "Without a volumizer, the roots will fall flat," says Normant. After every shampoo, massage an apricot-size dollop of lightweight mousse (we likePaul Mitchell Awapuhi Wild Ginger Hydrocream Whip) into the roots while they're damp to give hair some lift without turning it crunchy—even if your hair is thick and you've never needed to use a volumizer before. Skip the strong stuff, though. "Strong-hold styling products actually weigh down long hair," says Fugate.
