Honest expectations

What it does — and what it doesn't

We'd rather be straight with you than overpromise. Here's exactly what to expect.

What it does

  • Makes hair look smoother, shinier and softer
  • Tames frizz and flyaways through the day
  • Absorbs fast — no greasy, weighed-down feel
  • Works on every hair type, including colour-treated
  • A 10-second leave-in step — no rinsing

What it doesn't do

  • It won't grow hair or stop hair loss
  • It won't change or lift your colour — it's not a toner or dye
  • It's not a scalp treatment or a medicine
  • It can't permanently repair split ends — no product can
  • No overnight miracle — it's a finishing serum that's best with regular use

Soft and smells amazing
I love it! It smells really good. I use it at night before bed and the next day after I wash my hair it leaves it with movement and very soft. I'll definitely keep buying it.

Light, soft and silky
I really liked these — my hair feels light, soft and silky after using them. 40 capsules in the jar and a little goes a long way.

Smooth instantly
Frizz gone and my hair looks glossy without feeling heavy. Best results on damp hair right after washing.

Great for curly hair
Smells really nice. Tried it on my son's curly hair and it doesn't feel overly oily or greasy. The capsules twist open easily.

Perfect for colour-treated hair
My ends looked dry and dull before. After a week of one pearl a day they look so much healthier and shinier.

Silky and lightweight
Love that there's no rinsing. On my very thick hair it absorbs fast so I use two pearls, but the finish is lovely.

Silky, shiny — my 2nd order
These hair vitamins are wonderful — they leave your hair silky and shiny. This is the second purchase I've made and it arrived in good time.

Works from day one
They work from the very first application. One tip: if you live somewhere hot, keep them in the fridge so they stay nice and firm.

Frizz tamer
Static was wrecking my hair. A single pearl through the lengths and it's smooth and shiny again.

Honestly can't do without this product now — my hair always looks and feels great. 😍

Defines my curls without the crunch. Lightweight and no greasy residue.

Smells like jasmine
The scent is lovely — it reminds me of jasmine — and my hair feels soft and nice. Tip: don't use a whole capsule at once or it can feel a bit greasy; less goes further than you'd think.

Salon shine at home
Got compliments at work asking if I'd had a treatment. Just this!

Smells great, lasts ages
Lovely capsules and they smell great. They're generously sized, so I split one into two uses and it still works perfectly.
