The medical term for hair loss of any type.
Alopecia Androgenetic is the most common cause of hair loss in both men and women, it is caused by hormones and is typically hereditary.
Baldness is medically known as alopecia.
Common types of hair loss:
An autoimmune disease, where the immune system mistakenly attacks hair follicles. Identified as bald patches across the scalp, affecting both sexes equally. It usually occurs between the ages of adolescent and 30 years but can develop at any stage.
Also known as scarring hair loss, is the loss of hair with scarring. It can be caused by rare disorders that destroy the hair follicle, replace it with scar tissue and cause permanent hair loss.
Genetic Hair Loss
Commonly referred to as male or female pattern hair loss. The most common cause of hair loss in the UK. Pattern baldness in both men and women is a genetic condition. There is a reduction in the size of the affected hair follicles, resulting in a reduction in the diameter of the hairs that they produce. This accounts for the thinning of the hair and the widening of partings.
Typically caused by a disturbance to the hair growth cycle, causing the growing hairs (Anagen) to prematurely enter the resting phase (Telogen). It usually presents itself as excessive shedding or a normal amount of hair loss leading to gradual thinning. Women are mainly affected by this condition.
Known as cosmetic hair loss, caused primarily by prolonged or repetitive tension on the scalp hair e.g. frequently wearing your hair in a particularly tight ponytail, pigtails, or braids weakens/breaks hair.
Known as hair pulling disorder, is an impulse control disorder. Most common amongst children and women, causing hair loss through repeated pulling due to irresistible/obsessive impulses.
Dihydrotestosterone (DHT) is a by-product of the male hormone testosterone, produced naturally by the body. DHT inhibits hair growth and prevents nutrients reaching the hair follicle.
Finasteride is a synthetic chemical which works by lowering the enzyme that converts testosterone into dihydrotestosterone (DHT).
A South American plant that has been used in traditional medicine for centuries and its extracts have been shown to prevent hair loss in a clinical trial.
Minoxidil is a synthetic drug used to promote hair growth.
Provides the sulphur required for healthy collagen and keratin, which are both essential for healthy hair growth.

Parabens are a form of preservative, widely used in the cosmetic and personal care industry. The science part: parabens are esters, a compound molecule formed from acid and alcohol. Parabens are used to extend the shelf life of the product (with the right amount, bacteria and fungi cannot grow in it).
Does not contain sodium lauryl sulphate, a chemical/foaming agent used by many of the big brands in hair care.
The Hair Growth Cycle
The hair growth cycle has 4 phases - Anagen, Catagen, Telogen and Exogen.
Anagen (growth phase)
The growth phase in which 85% of hair is actively growing at any given time. This phase lasts 3 years on average and determines our length of hair.
Catagen (transition phase)
The transition phase in which the hair follicle detaches from the dermal papilla (the hair’s nutrient vessel) as the growth stage comes to an end. Around 1% of hair is in this phase and lasts no longer than 1-2 weeks.
Telogen Phase (resting phase)
The resting phase lasts around 3-4 months. Around 10-15 percent of hairs are in this phase. Whilst the old hair is resting, a new hair begins the growth phase.
Exogen Phase (shedding phase)
The shedding phase is part of the resting phase in which the old hair sheds. Around 50-150 hairs can fall out daily (a normal hair shedding amount).
