KeraHealth Details

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:

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
  • KerCysteine
  • Others

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.
Hair growth vitamins

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

KerCysteine 25% Others 75%

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

KerCysteine 55% Others 45%

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

KerCysteine 75% Others 25%

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

KerCysteine 25% Others 75%

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.*

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

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
