For colour-treated and dry hair: highlights, balayage, ombré, all-over colour and hair that feels rough or looks dull. It suits anyone who heat-styles often and wants protection that does not leave hair greasy or heavy.

It is a retail styling spray for home use. Because it is oil-free and light, it works on fine as well as thicker hair.

Coloured hair loses tone fastest when it is dry and repeatedly heat-styled. Hyloren Color Save Dream Hair Spray puts a weightless, heat-activated layer around each strand before the dryer or iron touches it, so moisture stays in and the cuticle is less exposed. Mon Platin designed it for colour specifically, adding protection against fading, humidity and sun, and kept it free of oils, formalin and parabens so hair stays light and glossy rather than coated.

Use before heat styling.

• On damp hair: spray evenly through the lengths before blow-drying.
• On dry hair: spray before using a flat iron.
• Hold the bottle 6 to 8 inches (15 to 20 cm) from the hair.
• Style as usual; leave in.

Pros:

• Oil-free, so it protects without making dry, coloured hair look greasy or flat.
• Covers several stressors at once: heat, humidity, colour fading and sun exposure, per the brand.
• Fine mist works on damp or dry hair, so it fits before a blow-dry or before flat ironing.
• Free of formalin and parabens.

Cons:

• Mon Platin does not publish a maximum temperature rating for this spray, unlike the Hyloren serums rated to 450°F.
• As an oil-free spray it gives a light finish; very coarse or very damaged hair may also want a serum or mask.
