Glossy hair equals healthy, well-moisturized hair, according to the experts. Consider using an effective weekly or monthly treatment (depending on your needs) to hydrate strands and keep them smooth and reflective.

Deep Conditioners

These concentrated treatments contain rich oil-based moisturizers to help alleviate dryness and seal the cuticles, says L.A.-based stylist Charles Dujic.

Best for: Hair that is styled with heat more than three times a week.

Hassle factor: Low. Use once a week in lieu of a daily conditioner; leave on for 20 minutes, then rinse.

Expert pick: Shu Uemura Moisture Velvet Nourishing Treatment for Dry Hair, $60, shuuemura.com for locations.

Hair Masks

A richer option, masks fill in weak areas on the hair shafts with proteins to create more even and shinier surfaces.

Best for: Chemically treated hair.

Hassle factor: Moderate. Apply a mask twice a week.

At-Home Glosses

The best formulas condition hair with oils and silicones and coat it with a reflective glaze that gradually washes out.

Best for: Brittle, beat-up hair.

Hassle factor: Low. Once a month, let sit for up to five minutes.

Professional Deep Treatments

An in-salon service combines the oils of a deep conditioner, the proteins of a mask, and the silicones of a glaze to boost hair’s health and brilliance. Once the mix is applied, you sit under a dryer to help the ingredients penetrate.

Best for: Extremely damaged hair.

Hassle factor: Moderate. The service takes about 20 minutes (plus travel time). If you want to skip the visit, the Warren-Tricomi Salon has developed a similar at-home version. Try Warren-Tricomi Repair Green Walnut Masque, $38, warrentricomi.com.
