KERCYSTEINE CLINICAL STUDIES

90 Days

50 Subjects

Five Tests

The KerCysteine clinical study was a randomized, parallel group, double-blind, placebo-controlled 90-day intervention study on 50 subjects with signs of damaged hair and nails conducted at a single site in Italy. The effects of both the active and placebo groups were measured on hair using five separate tests:

1. Pull test             2. Tensile strength      3. Amino acid composition
4. Brightness        5. Hair cycle (anagen/telogen)

HAIR PULL TEST

The pull test helps evaluate scalp hair loss. Gentle traction was exerted on a bunch of about 60 hairs in three areas of the scalp and the number of extracted hairs was counted. The dermatologist takes a few strands between his/her thumb and forefinger and pulls them gently.

  • 92% of the participants experienced less hair loss only after 1 month
  • 100% of the participants experienced less hair loss after 3 months
  • Participants experienced an average decrease of 47% of hair loss in only 3 months
TENSILE STRENGTH

The breakage resistance of a single hair fiber was evaluated by a dynamometer (Tensolab 2512A, Mesdan Lab). An average of 10 readings was made.

  • Subjects on placebo showed no statistical improvement of their hair strength at the end of the test period.
  • The active group that took KerCysteine showed a 10% improvement in hair strength after 3 months.

AMINO ACIDS

Keratin proteins derived from amino acids account for about 80% of the components which constitute human hair. Other components include water, lipids, and melanin. Since the scalp is skin, amino acids are essential to keep it well-nourished and ready to promote healthy hair growth. Amino acids such as L-cysteine, L-methionine and L-serine are known to promote hair growth.

SERINE

Serine is an amino acid produced by the body which performs a wide range of functions. Serine plays a role in the function of muscle formation and metabolism of fat and fatty acids. This among acid also plays a role in the production of Antibodies.

GLUTAMIC ACID

Glutamic acid is an amino acid needed for the synthesis of proteins. It is also essential for detoxification and therefore for a healthy body. Glutamic acid is needed for the synthesis of glutathione, among the most effective antioxidants in the body.

CYSTINE

A large portion of the Keratin is made of cysteine. Recent researches confirm that cysteine could reduce hair loss*. Even though our body could produce its own cysteine, this production can reduce due to many factors such as diet, pollution and stress.

METHIONINE

Methionine is an amino acid vital for the synthesis of Keratin, and Collagen. It’s a powerful antioxidant that improves hair follicle protection from oxidative stress. Recent research has shown that low levels of methionine could cause a decline in hair health and growth.*

BRIGHTNESS

The hair appearance was evaluated by a licensed dermatologist who assigned a value of one to three based on the subject’s hair brightness and lustre. A score of 1 is dull and devoid of brightness, a score of 2 is basically dull and not so bright, and a score of 3 is shiny and bright.

  • 33% of participants observed an improvement only after 1 month
  • 96% of the participant observed an improvement after 3 months
CLINICAL CLASSIFICATION OF HAIR BRIGHTNESS
HAIR CYCLE

ANAGEN (GROWTH STAGE)

TELOGEN (RESTING STAGE)

Anagen/telogen testing was performed by choosing a targeted area (mid-vertex) of approximately 1.8 cm2 for clipping hair. Close-up digital photographs were immediately taken after shaving and 2 days later. The two photographs were compared by software to determine if the hair was in Anagen phase (growing) or Telogen phase (final cycle of the hair).

  • 100% of participants saw an increase in Anagen after 3 months
  • 100% of participants saw a reduction in Telogen after 3 months
  • The percentile change of Anagen was 10x higher
