Anyone with frizz, dryness or dullness who wants shine without a greasy or heavy feel. Paul Mitchell lists it for all hair types and calls out dry, color-treated, lightened and damaged hair in particular.

Fine hair should use a very small amount; thick or coarse hair can use it twice, once on towel-dried hair and again when dry. It suits home use and salon finishing alike.

Frizz and dullness usually come from a rough, dry cuticle. This oil coats and seals the hair with a light silicone film, so strands lie flatter and reflect more light, while the dry-touch finish avoids the greasy look heavier oils can leave. Because it works on damp or dry hair, one bottle covers prepping a blow-dry and taming flyaways later in the day.

• To prep: apply a small amount to clean, damp hair and style as usual.
• To finish: smooth a small amount over dry hair to eliminate frizz and add shine.

On finer hair, less is more. On denser, coarser hair, apply to towel-dried hair and again once hair is completely dry.

Pros:

• Dry-touch texture that absorbs quickly instead of sitting on the hair.
• Works two ways: as a prep on damp hair or a finisher on dry hair.
• Vegan, color safe, paraben free and made without gluten, per Paul Mitchell.

Cons:

• Silicone-based, which matters if you avoid silicones.
• Too much can weigh down fine hair, so start with a small amount.
• No heat-protection claim from the brand.
• Contains fragrance and fragrance allergens.
