Extract of pea shoots for the treatment of hair loss
Millions of people around the world suffer from hair loss and for many, this is also associated with significant mental health problems. They wish for a simple and effective treatment, but currently available treatment options are often unsatisfactory due to side effects and / or limited efficacy. In a recent study pea germ extract was tested as a hair loss remedy.
The external application and also the intake of an extract from pea sprouts can significantly reduce hair loss, according to a new study published in the journal "Phytotherapy Research". Researchers at Mibelle Group Biochemistry conclude that pea seed extract is an effective "way to safely promote hair growth and reduce hair loss in people who have excessive hair loss."
Hair loss to some extent normal
Healthy hair fulfills many physiological functions and is an important component of identity, according to the research team. Although we lose about 100 hairs daily, they usually grow to the same extent. Due to cyclical loss and new hair growth, the number of hair remains relatively constant. However, if the proportion of hair in the so-called telogen phase (resting phase of growth) increases and the proportion of hair in the anagen phase (growth phase) decreases, a diffuse hair loss can be observed, explain the researchers.
Many factors can cause hair loss
Slowly progressive diffuse hair loss affects about every second person at the age of 50 years. A variety of factors can play a role here, reports the research team. Thus, hormonal changes, malnutrition, stress, drug intake and hereditary predisposition are known as risk factors. While there are a number of therapies (such as finasteride), there is a great need for "safe, natural ingredients to relieve hair loss, given the side effects".
External application of pea germ extract
Previous studies have already shown that the extract of pea shoots has been shown to improve hair density when applied topically (externally), the researchers report. The current study examined the underlying processes by using a liquid containing two percent pea extract (AnaGain ™).
Altered gene expression by the extract
The fluid was applied to a defined head skin zone of ten volunteers (four women and six men) and the expression of certain genes relevant to hair (fibroblast growth factor-7 and noggin) recorded. The researchers were able to prove that the gene expression is significantly increased by the extract (56 or 85 percent).
Ingesting the pea extract is also effective
In a follow-up pilot study of 21 volunteers, the researchers also investigated whether extract from pea shoots is effective even when consumed as a dietary supplement. "After two months of treatment with the pea extract, 95 percent of participants experienced a reduction in hair loss" and already "within the first month, the average number of lost hair fell by 33.9 percent," the researchers report.
Hair loss significantly reduced after just 28 days
Although the results of the current study still need to be reviewed in further studies with significantly larger numbers of participants, the extract of the pea shoots seems a promising treatment for hair loss. The research team emphasizes that "daily intake of 100 mg pea seed extract (AnaGain ™ Nu) significantly reduces hair loss after just 28 days of treatment." In addition, there are no known undesirable side effects. (Fp)
