Paul Mitchell lists this shine spray as suitable for all hair types. It is a finishing product, so it suits anyone who has already blow-dried, straightened or curled their hair and wants a glossier surface without changing the shape of the style.

It contains no hair color or developer and needs no mixing, so it is easy for home use as well as in the salon. Very fine or oily hair may show the silicone-based shine more readily than thick or dry hair, so start with a light application.

Most shine products are creams or oils worked in before styling. This one is a fine aerosol mist meant for the very last step, which is why it can add gloss to an already-finished blowout or curl without weighing it down. The shine comes mainly from lightweight silicones that smooth the surface of the hair, and the keratin proteins and panthenyl ethyl ether in the formula are there to condition. The awapuhi root extract is the line's signature ingredient, harvested at Paul Mitchell's Hawaii farm according to the brand.

Apply to the finished style, after you have finished drying and styling. Paul Mitchell gives this single instruction, so build up gradually: a light mist first, then a little more only if you want extra gloss.

What works well

• Light silicones give a reflective finish without the heavy feel of a serum.
• Goes on last over a finished style, so it will not disturb the shape or add stiff hold.
• The brand says it helps protect hair during heat styling.

Limits to know about

• It adds shine only: no repair, hold or volume.
• Silicone-based, so it will not suit anyone trying to avoid silicones.
• Aerosol with alcohol denat. and added fragrance, which some people with sensitive scalps or skin prefer to avoid.
