What is keratin?

Keratin is a protein - and not just any protein. It's the main structural building block of your hair (about 80%), your nails (almost entirely) and the outer protective layer of your skin. Think of keratin as the scaffolding that keeps hair strong, nails resilient and skin firm and smooth. The body naturally produces keratin, but production can slow down over time - which is where a daily nutritional top-up can help keep the scaffolding well-stocked.

Why hydrolysed keratin?

Here's the catch with keratin - in its natural form, it's a large, tough protein that the body struggles to absorb. That's where hydrolysed keratin comes in. "Hydrolysed" simply means the protein has been broken down into smaller peptides that the body can actually absorb and use. KeraGLO® is extensively hydrolysed (not just partially) making it significantly more bioavailable than many other keratin supplements on the market. More absorption means more of that keratin goodness making its way to where your body can put it to work.

Beauty from within: a simple daily habit

Topical hair masks, nail polishes and skincare all have their place, but true beauty support starts on the inside. This formula is a lovely fit for:

  • Anyone wanting to nourish hair prone to dryness, brittleness or breakage
  • Those looking for daily nutritional support for strong, healthy nails
  • Adults seeking beauty-from-within nutrition to complement their skincare routine

  • Mature adults wanting to support their natural keratin nutrition
