Every morning the same glance in the mirror: When will your hair finally grow longer? Whether it's a disastrous haircut or the dream of a luscious mane – the question of monthly hair growth is on the minds of many women. In this article, you'll learn which factors influence your personal growth rate and how you can naturally support your hair growth with the right combination of internal and external care.
Our hair goes through a complex cycle with three phases:
• The anagen phase (growth phase): During this phase, your hair grows an average of 1-1.5 cm per month and can last up to seven years. This phase is crucial for the maximum hair length you can achieve.
• The catagen phase (transition phase): During this two-week phase, growth stops and the follicle shrinks.
• The telogen phase (resting phase): Here the hair remains in the follicle for about three months before it falls out and the cycle begins again.
Approximately 85-90% of your scalp hair is in the active growth phase at any given time. This individual distribution is largely determined by your genetics, but can be influenced by external factors such as stress, diet, and hormonal fluctuations. The female hormone level plays a particularly crucial role – estrogen prolongs the growth phase, while testosterone can shorten it.
Female hormones, especially estrogen, lengthen the growth phase and promote full, strong hair. During pregnancy, many women experience improved hair growth due to increased estrogen levels. Conversely, hormonal changes during menopause or in cases of PCOS can lead to hair loss. Thyroid hormones also affect hair health – an underactive thyroid slows down metabolism and thus hair growth.
Optimal nutrient supply is essential for healthy hair growth:
• Proteins (at least 0.8g per kg body weight daily): Provide the building blocks for keratin
• Iron: Supports oxygen transport to the hair follicles
• Zinc: Regulates sebum production and supports cell division
• B vitamins: Promote cell renewal and keratin production
• Vitamin D: Activates dormant hair follicles and promotes new hair growth
Tru Cosmetics' Hair Boost Caps combine these essential nutrients in a vegan formula with millet, horsetail and ginseng to holistically support your hair growth.
Current research confirms the effectiveness of certain ingredients in promoting hair growth:
• Caffeine: It intensely stimulates the hair follicles and demonstrably prolongs the anagen phase.
• Peptides such as Acetyl Tetrapeptide-3: Proven to strengthen hair anchorage and visibly reduce hair loss.
• Biotin: As a coenzyme, it supports keratin production and improves hair structure.
• Niacinamide: Widens blood vessels and improves the nutrient supply to hair roots.
Tru Cosmetics' Hair Growth Serum utilizes these scientifically proven active ingredients in a highly concentrated formula that works directly on the scalp. For optimal results, it should be used for at least three months – the time your hair needs for a complete growth cycle.
Eyelashes grow an average of 0.12–0.14 mm per day and have a significantly shorter growth phase of only 30–45 days. This explains why eyelashes reach a natural maximum length of 8–12 mm. Tru Cosmetics' Eyelash Serum Soft utilizes a specialized peptide complex with Myristoyl Pentapeptide-17, caffeine, and biotin to extend the growth phase and increase eyelash density—without hormonal prostaglandins that can cause skin irritation.
Eyebrows follow the same growth cycle as head hair, but with a significantly shorter anagen phase of only 30-45 days. Tru Cosmetics' Brow Serum contains a special prostaglandin derivative that specifically extends the growth phase, resulting in fuller brows. The combination with biotin and caffeine further strengthens the hair roots and promotes a healthy hair structure.
Your hair grows an average of 1–1.5 cm per month – and with the right care, you can optimally support this process. The key lies in a combination of high-quality external care products and nutrient-rich internal nourishment. With the Hair Growth Serum and Hair Boost Caps from Tru Cosmetics, you give your hair exactly the support it needs for strong, healthy growth.
Consistency is key for visible results – you'll notice the difference after about three months.
