    Male pattern baldness

    Products for hair loss*

    More than 50 % of all men suffer from hair loss. The reasons and causes for this are varied. However, classic hair loss is hereditary in 80 % of men (androgenetic alopecia). This means that hair loss is largely genetically predetermined.

    The good news: Hereditary hair loss can be counteracted, and you can do this without medication.

    Stages 2 to 5 of the Hamilton-Norwood Scale

    In many cases, hair loss and balding in men follow a specific pattern. The Hamilton-Norwood Scale, for instance, outlines various types and stages of hair loss.

    Hair loss in men often starts at the temples and the forehead (receding hairline). As it progresses, the hair becomes thinner at the crown and then across the entire scalp.

    Causes of Hair LossCauses of Hair Loss: DHT as a Cause of Hereditary Hair Loss

    Chemical structural formula of dihydrotestosterone (DHT) as a possible cause of hereditary hair loss in men.
    Structural Formula of Dihydrotestosterone (DHT)

    Dihydrotestosterone (DHT), an active metabolic product of testosterone, is partly responsible for genetically determined hair loss.

    Each hair goes through a three-stage growth cycle, during which it falls out and regrows, ensuring that not all hair grows or falls out at the same time.

    The Three-Stage Hair Growth Cycle

    Shortening of the growth phase activates the shedding process

    In people with hereditary hair loss, the duration of the growth phase gradually shortens, and the shedding phase begins earlier. This process is triggered by dihydrotestosterone (DHT).

    Prevention with Caffeine ShampoosPrevention with Caffeine Shampoos: Prevent with Caffeine Shampoos & Liquids

    Hereditary hair loss is often caused by overly sensitive hair roots that react to dihydrotestosterone (DHT). Caffeine can counteract this by stimulating the hair root and boosting the energy metabolism. By extending the growth phases of the hair roots, hair growth is supported well into old age.

    Caffeine stimulates the hair roots

    Caffeine has been known for more than 20 years for its growth-stimulating effect on hair roots. It inhibits the breakdown of the intracellular messenger cAMP. As a result, more energy is available to the cells and cell growth is stimulated.

    Caffeine is therefore the most researched active ingredient of plant origin against hereditary hair loss.

    Complementary active ingredients

    Zinc and niacin promote energy metabolism and can improve nutrient supply to the hair roots.

    ConclusionConclusion: Prevention is better than cure

    Men with a family history of hair loss are likely to have a genetic predisposition and are more likely to develop baldness themselves.

    It doesn't have to come to that if you start using caffeine early on. Alpecin Caffeine Shampoo keeps hair healthy and counteracts the negative effects of DHT at the hair root. Daily use can break the vicious cycle and ensure healthy, full hair. If you don't want to wash your hair every day, you can also use Alpecin Caffeine Liquid.

    ** in vivo study, n=15 participants with hereditary hair loss

    • Phase 1Phase 1: Anagen Phase (Growth Phase)

      The hair follicles divide rapidly and form new hair; the hair grows about 1 cm per month; around 81 % of the hair is in this phase.

    • Phase 2Phase 2: Catagen Phase (Transition Phase)

      The hair stops growing, the cell matrix stops producing cells, causing the follicles to narrow at the lower part; around 3 % of the hair is in this phase.

    • Phase 3Phase 3: Telogen Phase (Resting Phase)

      After 2 – 6 months, the hair falls out, the hair root can recover, and then form a new hair; around 18 % of the hair is in this phase, also known as club hair.
