    Hamilton-Norwood scale

    Hair loss and balding often follow a specific pattern. The Hamilton-Norwood scale shows various stages. Hair loss usually starts at the temples and forehead, then spreads to the back of the head, and eventually over the entire scalp.

      Growth cycleGrowth cycle: The three-stage hair growth cycle

      Your hair goes through a growth cycle in three phases.

    • Schematic representation of a hair in the growth phase of the hair growth cycle.

      Phase 1Phase 1: Anagen phase (growth phase)

      The hair follicles divide quickly and form new hair; within a month the hair grows about 1 cm; about 81 % of the hair is in this phase.

    • Schematic representation of a hair that is no longer firmly anchored in the hair shaft, symbolising the transition phase in the hair growth cycle.

      Phase 2Phase 2: Catagen phase (transition phase)

    • Schematic representation of two hairs, with one hair no longer firmly anchored in the hair shaft and the second hair falling out, symbolising the resting phase of the hair growth cycle.

    Caffeine as hair loss preventionCaffeine as hair loss prevention: 80 % of men with classic hair loss have hereditary hair loss.

    Any disturbances in the growth cycle can lead to reduced nutrient supply, active growth phase, and size of hair follicles, resulting in increased hair loss.

    is often caused by hypersensitive hair roots that react to dihydrotestosterone (DHT). DHT binds to the androgen receptor, leading to shortened growth phases and thinner hair.

    Caffeine can counteract this by stimulating the hair root and boosting the energy metabolism.

    • DMG: Innovative active ingredient for optimal nutrient supply

      Nutrient supply is crucial for healthy hair growth. Fine blood vessels transport oxygen and nutrients to the hair roots. In hereditary hair loss, this supply can be impaired by reduced microcirculation. DMG, a novel active ingredient, stimulates microcirculation and can thus optimise the supply. Hair weakened by nutrient deficiency can be supported in growth again. Additionally, DMG has anti-inflammatory properties and can counteract micro-inflammations associated with hair loss.

    Other types of hair lossOther types of hair loss: Hair loss in focus

    Stress, whether due to lack of sleep or personal problems, can lead to hair loss. Heavy physical exertion increases the body's energy requirements, which means that the hair roots are not sufficiently nourished. This can lead to thinning hair and hair loss.

    Diffuse hair loss is widespread. In contrast to hereditary hair loss, the hair in diffuse hair loss becomes thinner overall and there is no typical progression. The hair loss is not limited to certain areas (back of the head or forehead) but spread out evenly across the scalp.

    The reasons for diffuse hair loss can vary: physical or emotional stress, medication, or illness. In any case, the hair roots are not sufficiently supplied with nutrients and energy, as both are needed elsewhere in the body. The lack of energy then causes the hair to fall out and become thinner.

    If hair loss stems from illness or certain medications, you should always consult a doctor.

              Find out why coffee is not suitable for hair care and why you should use a caffeine shampoo instead.

              The hair stops growing, the cell matrix stops producing cells so that the follicles in the lower area constrict; around 3 % of hairs are in this phase.

              After 2 - 6 months the hair falls out and the hair root can recover and subsequently form a new hair; approx. 18 % of hairs are in this phase.
