Damaged, fragile, chemically treated and naturally coarse hair that frizzes, looks dull or has visible split ends.

Works on damp or dry hair, so it suits both blow-dry routines and air-dried styles. Fine hair should use a very small amount on the ends only.

A serum is the quickest way to make rough, frizzy lengths look polished, and this one is matched to the 700 Keratin & Kale line, so it suits hair already following that repair routine. A pump or two before drying makes brushing and styling easier, and a touch afterwards calms flyaways without a heavy feel.

• Towel-dried hair: rub 1 to 2 pumps between your palms and work through the mid-lengths and ends
• Air dry, or blow-dry and style as usual
• Dry hair: apply a small amount to the mid-lengths and ends to smooth frizz and add shine

Use before heat styling for a smoother finish, or after styling as a light finishing touch.

Pros:

• Immediate smoothing and shine from a silicone base
• Small amounts go a long way, so 65 ml lasts
• Works before heat styling or as a finishing touch on dry hair
• Colour-safe

Cons:

• Silicone serums can build up without occasional clarifying
• Too much on fine hair looks flat or oily
• Contains fragrance and allergens including limonene, linalool and citral
