- Hair that feels heavy or flat.

- Visible buildup of styling product residue.
If you notice one or more of these signs, it’s probably the right time to shampoo—even if it’s only been a day.

- Oily hair may require more frequent washing to prevent excess sebum.
- Dry or curly hair can usually go longer between washes, since sebum doesn’t travel as easily along the hair shaft.
