Blonde hair, lightened or natural, that looks dull, frizzy or dry at the ends. Oligo gives medium to thick hair extra attention, although the brand calls the formula lightweight; fine hair should start with a single drop.

A retail finishing product for home styling.

Lightened blonde hair often looks matte and frizzy even when it is well conditioned. This oil is the finishing step of Oligo's HYD routine: a light, fast-absorbing layer that smooths the surface for visible shine and controls flyaways, with hyaluronic acid and the line's plant oils for softness. It can be used before or after styling, which makes it more flexible than a serum meant only for one stage.

Place a small amount of oil (start with 1 to 2 drops) in your hands and rub them together.

Apply from mid-lengths to ends.

Use on damp or dry hair, before or after styling.

Pros:

• Quick shine and frizz control on damp or dry hair
• A small amount covers the lengths, so the 100 ml bottle lasts
• Silicone slip gives a smooth, glossy finish
• Pairs with the 18-in-1 Beautifier

Cons:

• Too much can make fine hair look flat or oily
• Silicone-based, which some buyers prefer to avoid
• No heat-protection claim on the label; use the 18-in-1 Beautifier underneath for that
