What is Pretty Crystal Serum?

Pretty Crystal Serum by Edelstein is a leave-in shine serum (liquid crystals) with linseed oil in a silicone base that gives dry, brittle or treated lengths and ends a smooth, glossy finish, in a 120 ml bottle for the salon and for home use. A few drops are spread on towel-dried hair before styling, or on dry hair as a finish, with no rinsing. The light, fast-drying texture leaves a non-greasy shine, and at about 2 ml per application a bottle gives around 60 uses.

Specifications

Who Pretty Crystal Serum is for

• Dry or brittle lengths and ends that look dull.
• Coloured or chemically treated hair that needs a shiny, smooth finish.
• Salons that finish a blow-dry or a flat-iron style with a few drops for shine.
• Home use on dry hair for less visible frizz and flyaways between washes.

For an argan oil serum, or a keratin fluid within a care routine, see the comparison below.

Key ingredients

• Dimethiconol: a silicone that coats the hair surface with a smooth film, helps detangling and adds shine.
• Linum Usitatissimum (Linseed) Seed Oil: linseed oil, which helps keep the lengths soft and supple.
• Methyl Hydrogenated Rosinate: a film-forming ingredient that helps the lengths look smooth and compact.
• C13-14 Isoparaffin: a light ingredient that gives the serum its fast-drying, non-greasy texture.

Results

After application, the hair detangles more easily, the lengths look smoother and shinier, and split ends, frizz and flyaways are less visible. Used in small amounts and kept away from the roots, the serum leaves no greasy finish.

How to use Pretty Crystal Serum

1. Wash the hair and towel-dry it.
2. Put a few drops (about 2 ml for medium-length hair) in the palm and spread them over the lengths and ends with the hands or a wide-tooth comb, keeping away from the roots.
3. Style as usual. Do not rinse.
4. On dry hair, a few drops on the ends finish the style; before a flat iron or curling iron, use a dedicated heat protectant.
