“Achieve stronger, healthier hair with the Philip Kingsley Density Amino Acid Protein Booster Capsules, a vegan and cruelty-free blend of key nutrients and vitamins.” - Darcey, Escentual Beauty Team.


Why You’ll Love The Philip Kingsley Density Amino Acid Booster:

  • Daily supplement to support the maintenance of healthy hair, nails and skin.
  • Packed full of key nutrients and vitamins to improve overall hair condition.
  • Encourages the formation of proteins to strengthen your hair.
  • Contains key actives, such as vitamin C, biotin, selenium and copper.
  • Vegan, cruelty-free formula.


What You Need To Know:

Your hair health can be impacted by a number of factors, such as poor nutrition, stress, medication, overstyling and clinical treatments. That’s where the Philip Kingsley Density Capsules come in! Amino acids combine to form proteins that work as the building blocks of your hair. In fact, 85% of your hair is made up of a protein called Keratin. So, the Amino Acid Capsules are jam-packed with key nutrients to support your hair's healthy hair from the inside out.

Each capsule contains a blend of essential and non-essential amino acids to encourage the production of keratin for healthy, shiny and thick hair. Philip Kingsley’s optimised blend of amino acids sits alongside vitamin C, biotin, selenium and copper, resulting in a nutrient-rich cocktail of actives for your skin, hair and nails.


Why It’s Escentual:

If you loved the best-selling Trichotherapy PK4 tablets, you’ll love the new-and-improved replacement: the Philip Kingsley Density Amino Acid Protein Booster. These capsules sport the same format, size and shape as the previous PK4 capsules, featuring a smooth coating that makes them super easy to take daily. Better than ever, the Amino Acid Protein Booster now includes antioxidant vitamin C for improved collagen formulation, alongside biotin selenium and copper to contribute to the maintenance of your hair health and colour.

Vegan, vegetarian and cruelty-free, everyone can support healthy hair from the inside out. Trichologists at Philip Kingsley recommend three months of use for visible improvements in hair quality, although an improvement in nails can be seen before; this bottle contains 120 tablets for just over two months of use.


The Best Way To Use It:

Take two capsules, twice a day. Do not exceed the daily recommended amount.
