The Agent Nateur Holi (Locks) Hair Growth Serum is a high potency, overnight topical strengthening hair serum. This anti-fall serum is a treatment oil, not a styling oil.

Backed by advanced hair science and clinical studies  this serum contains four proven active ingredients, and anti-hair fall, shine-inducing compounds to help stimulate and encourage healthier looking hair.

When applied topically for at least 12 weeks, this overnight strengthening serum helps your hair to appear denser, thicker and fuller, all without the use of silicones.

Formulated to help detangle and make your hair incredibly silky smooth, just leave on the hair for a minimum of 8-12 hours and then wash, style and finish with hair (silk) peptides. Best for:

  • fine hair
  • dull, damaged hair
  • split ends
  • dry hair and scalp
  • hair that breaks easily

Key ingredients in Agent Nateur Holi (Locks) Hair Growth Serum include:

  • Follicusan™ - revitalises and promotes thicker looking hair. Patented, trademarked and science-backed, this is a milk-based bioactive, which clinical studies have proven to stimulate the appearance of dermal papilla cells on the scalp.
  • Capixyl™ - a peptide (acetyl tetrapeptide-3) that is combined with a plant-based red clover extract, densely rich in Biochanin A, these ingredients work together to promote healthy hair and stimulate new hair.
  • Redensyl™ - called the ‘human hair galvaniser’ and targets the root causes of unhealthy hair.
  • Beracare ARS Hair Serum™ - a natural complex packed with properties to deliver an intense glow for your hair. Made up of naturally derived Passiflora Edulis Seed, Oryza Sativa Rice Bran and Euterpe Oleracea Fruit Oil and delivers the ultimate gloss, softness and shine for your hair.
  • Kalahari - packed with linoleic acid and vitamin E, is a nourishing and hydrating compound, ideal for skin cell recovery, while also controlling frizz, reducing split ends and giving hair a healthy-looking shine.
  • EGCG Green Tea - Naturally derived this acts to prevent damage to the hair and scalp. Studies indicate that the polyphenols found in green tea, known as catechins, infuse hair strands with essential nutrients that support the hair growth cycle.
  • Bhringraj - an ayurvedic herb, derived from the sunflower family, is another shine-inducing ingredient in our strengthening hair serum. High in Vitamin E and packed with flavonoids, phytosterols, and coumestans, natural compounds that work together to nourish dense and voluminous hair follicles. Helps to contribute to soft and shiny hair, as well as a nourished scalp.
  • Horsetail , Crambe Abyssinica Seed, Monoi, Passiflora Edulis Seed and Hibiscus Rosa-Sinensis Plant to promote healthier hair.

How To Use

Shake before use.

Use 1 to 2 droppers for whole-head application.

Massage into scalp all the way through the ends of your hair. Apply up to 4 times a week. Gently massage the serum in circular motions for about 15 minutes and leave  for at least 30 minutes. Best when used overnight. Wash and condition hair after use.

Founder Tips: Leave this overnight for 8-12 hours and then rinse it out. If I apply it during the day, I towel dry my hair, I apply Holi (Locks) from my scalp to the mid-section of my hair, apply Hair (Silk) to the mid-section to ends of my hair and then rinse it out at night.

*In case of contact with eyes or stinging of the skin, rinse thoroughly with water.
