There are some problems, like achieving peace on earth, that you can't solve today. But with the help of Wendy Iles, a celebrity stylist in Los Angeles, you can conquer these common, stubborn hair issues fast (because what mom's got time to fuss with her mane?). Read on.

Hair issue: Fine, flat hair

What you need: Very little -- too much goop will further flatten hair. Shampoo, conditioner, and a thickening body spray.

We love: Pantene Pro-V Full & Thick Shampoo and Conditioner ($3.99 each); Paul Mitchell Volumizing Spray ($11.50, paulmitchell.com for salon locations)

Hair issue: Straight hair that gets frizzy on top

What you need: A good blow-dry lotion, says Iles. This will help smooth hair down and keep it sleek.

We love: Redken Satinwear 02 Blow-Dry Lotion ($15) or Dove Heat Defense Therapy ($3.96)

Hair issue: Curly or wavy hair that gets frizzy all over

What you need: An anti-frizz serum, curl-defining spray, or a leave-in conditioner, says Iles.

We love: John Frieda Frizz-Ease Serum ($9.99) or TRESemmé Flawless Curls Hydration Lotion Crème ($4.49)

Hair issue: Straight hair that gets dry and dull-looking

What you need: A nondrying shampoo and conditioner, ideally free of moisture-sapping sulfates.

We love: L'Oréal EverPure Moisture Shampoo and Conditioner ($6.99 each)
