One bottle, two opposite jobs. Straight N' Curl is a 4 oz styling serum you can use to smooth hair out under a dryer or a flat iron, or scrunch through towel-dried hair to bring curl forward. The technique decides the result rather than the product.

Emu oil and buriti fruit oil carry the moisture, and the formula is paraben-free. It goes on light enough to leave hair feeling breathable rather than coated, which is what stops a shine serum turning into a grease serum by the afternoon.

  • For a sleek finish, work small amounts through damp sections, then blow dry or flat iron
  • For curl, distribute through towel-dried hair and scrunch, or use a diffuser
  • Either way, less product across more sections beats more product across fewer

It also gives protection during heat styling and against the weather, which is worth having on a serum you reach for before a flat iron. Good for anyone whose hair does two different things depending on the week.

Application tips

Decide the finish before the bottle is open, because the same serum does both jobs and your hands do the deciding.

For smooth, thin coverage on damp sections and then tension from a brush or an iron. For curl, towel dry first, then scrunch in handfuls and diffuse. Thin coverage across many sections beats a heavy dose on a few. Do not add more halfway through drying.

Results

Hair reads glossy rather than oily, and it still feels like hair when you touch it, which is not a given with a shine serum four hours in.

Straightened lengths stay smooth and flat. Scrunched hair comes up with definition and some elasticity in the curl. It sits between the hair and a hot tool, and it holds off the frizz that damp weather brings.
