If repeated damage has caused your straight hair to fall flatter than a pancake, you need a bodifying boost that will add moisture without weighing hair down. Try this regimen to pump up your hair’s volume and leave you with touchable, noticeably fuller tresses.

Shampoo with Charles Worthington’s Big Hair Body Beautiful Shampoo ($3) or Jonathan Product’s Shampoo Serious Volume Voluminizing Shampoo ($20), then condition with Charles Worthington’s Big Hair Full Volume Conditioner ($3) or Jonathan Product’s Condition Serious Volume Voluminizing Conditioner ($22).

Before styling, while hair is wet, spritz Redken’s Body Full Weightlifter ($13) or apply some of Got 2b’s Sexy Voluptuous Volume Mousse ($6) on hair’s roots for volume, then style. Once your hair is dry, smooth the ends by using a Ted Gibson Hair Sheet ($25).

To maintain hair’s softness, once a week, apply a hydrating hair mask like Stephen Knoll’s Deep Treatment Hair Mask ($43) or Kerastase’s Nutrive Masquintense Intense Enriching Treatment ($45).
