The Hidden Secrets of the Hair Growth Cycle (and Why It Matters)
Posted by Amjad on 4th Sep 2025
Hair loss confuses many people, but there is a clear science behind it. Every strand on your head follows a growth cycle. Once you understand this cycle, you can see why some hair falls, why thinning happens, and how proven treatments like Minoxidil support regrowth.
What Is the Hair Growth Cycle?
Your hair does not grow all at once. Each strand follows its own timeline. Some are growing, some are resting, and others are shedding. This repeating cycle is what keeps your hair renewing throughout life.
The Four Stages of Hair Growth
1. Anagen (Growth Stage)
- The active growth stage.
- Lasts 2–7 years depending on genetics.
- About 80–90% of your hair is in this stage.
- The longer this stage lasts, the longer hair can grow.
2. Catagen (Transition Stage)
- A short stage of 2–3 weeks.
- The follicle shrinks and stops producing new cells.
3. Telogen (Resting Stage)
- Lasts around 3 months.
- About 10–15% of your hair is in this stage.
- Old hair rests while new hair starts forming underneath.
4. Exogen (Shedding Stage)
- Old hair falls out.
- Normal to lose 50–100 strands each day.
- Makes room for new hair to emerge.
Why the Hair Growth Cycle Matters
When the growth stage (anagen) shortens, hair becomes thinner and weaker. More hairs shift into the resting stage, leading to visible thinning.
Several factors disturb this balance:
- Hormones, especially DHT, which shrinks follicles.
- Stress and poor sleep.
- Poor diet.
- Age and genetics.
Treatments such as Xandrox Minoxidil 15% with Azelaic Acid extend the growth stage and reactivate weaker follicles, helping restore thicker hair.
Tips for Supporting a Healthy Hair Cycle
- Eat well: Protein, iron, zinc, and vitamins like biotin support strong hair.
- Care for your scalp: Massage gently and avoid harsh shampoos.
- Stay consistent with treatment: Daily use of Minoxidil makes the most difference.
- Manage stress: High stress can push hair into shedding early.
