Menthogen
Menthogen is a topically applied scalp stimulant which is claimed by its manufacturers to treat itchiness and irritation of the scalp as well as combating certain types of alopecia. Since its development (see history below) Menthogen has been further developed in the UK by a team of trichologists. Menthogen's scalp cooling effect occurs due to the presence of menthol and alcohol within the formula. Other ingredients are claimed to counteract the effects of androgens said to contribute to both male and female pattern hair loss. History Menthogen was originally created and developed by Mr F.J. Cunningham MIT (Lond) MAE FRSPH at his dispensary in Castleton, Rochdale, Greater Manchester in 2002 for in clinic use with private clinic patient's within his trichology centre. A year long private double-blind study was undertaken to study the assumed benefits of the formulation. Science Menthogen contains vasodilators; stimulators which act upon blood capillaries and hair bulbs (roots) w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichology
Trichology is the study of the hair and scalp. The term derives from Ancient Greek θρίξ (''thríx''), "hair" and -λογία ''-logia''. In most jurisdictions the title of a ''trichologist'', not the field of trichology, is considered a para-medical discipline. The Institute of Trichologists was founded in 1902. The first journal for the field, International Journal of Trichology, was founded in 2009.

Alopecia
Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. Typically at least the head is involved. The severity of hair loss can vary from a small area to the entire body. Inflammation or scarring is not usually present. Hair loss in some people causes psychological distress. Common types include male- or female-pattern hair loss, alopecia areata, and a thinning of hair known as telogen effluvium. The cause of male-pattern hair loss is a combination of genetics and male hormones; the cause of female pattern hair loss is unclear; the cause of alopecia areata is autoimmune; and the cause of telogen effluvium is typically a physically or psychologically stressful event. Telogen effluvium is very common following pregnancy. Less common causes of hair loss without inflammation or scarring include the pulling out of hair, certain medications including chemotherapy, HIV/AIDS, hypothyroidism, and malnutrition including i ...

Double-blind
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints. During the course of an experiment, a participant becomes unblinded if they deduce or otherwise obtain information that has been masked to them. For example, a patient who experiences a side effect may correc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytohormones
Plant hormone (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones. Went and Thimann coined the term "phytohormone" and used it in the title of their 1937 book. Phytohormones occur across the plant kingdom, and even in algae, where they have similar functions to those seen in higher plants. Some phytohormones also occur in microorganisms, such as unicellular fungi and bacteria, however in these cases they do not play a hormonal role and can better be regarded as secondary metabolites. Characteristics The word hormone is derived from Greek, meaning ''set in motion''. Plant hormones affect gene ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
