Why has your hair stopped growing and what to do?
By Jo Phillips
Hair growth can be a complex and frustrating issue for many people. Numerous factors can contribute to slowed or stopped hair growth, including genetics, hormonal imbalances, nutritional deficiencies, and stress. Understanding the root cause of stunted hair growth is crucial for finding an effective solution and restoring healthy hair.
Age plays a significant role in hair growth patterns. As we get older, our hair naturally grows more slowly and may become thinner. However, sudden changes in hair growth, particularly in younger individuals, often indicate an underlying issue that requires attention. Hormonal imbalances, such as thyroid disorders, can significantly impact hair growth and overall hair health.
Proper nutrition is essential for maintaining healthy hair growth. A diet lacking in essential vitamins and minerals, particularly iron, protein, biotin, and zinc, can lead to hair thinning and reduced growth. Incorporating nutrient-rich foods like spinach, eggs, berries, and beans into your diet can help promote hair growth. In some cases, using a hair growth stimulating serum may also be beneficial in supporting healthy hair growth and addressing specific scalp concerns.

Understanding Hair Growth
Hair growth is a complex biological process influenced by various factors. It involves intricate cellular mechanisms and cycles that determine the length, thickness, and overall health of our hair.
Anatomy of Hair Follicles
Hair follicles are tiny, sac-like structures in the skin that produce and grow hair. They consist of several layers, including the dermal papilla, hair matrix, and outer root sheath. The dermal papilla contains blood vessels that nourish the follicle and deliver essential nutrients.
Hair follicles cycle through active growth and rest periods. During active phases, cells in the hair matrix rapidly divide, pushing older cells upward to form the hair shaft. This process creates the visible part of hair above the skin’s surface.
Stages of the Hair Growth Cycle
The hair growth cycle consists of four main phases:
- Anagen (growth phase): Lasts 2-7 years
- Catagen (transition phase): Lasts 2-3 weeks
- Telogen (resting phase): Lasts 3-4 months
- Exogen (shedding phase): Occurs at the end of telogen
During anagen, hair actively grows. In catagen, growth stops and the follicle shrinks. Telogen is a resting period, while exogen involves the shedding of old hairs as new ones begin to grow.
Factors Affecting Hair Growth
Numerous factors can impact hair growth:
- Genetics: Determines hair texture, color, and growth patterns
- Hormones: Influence follicle sensitivity and hair production
- Age: Hair growth typically slows with aging
- Nutrition: Deficiencies in protein, iron, zinc, and biotin can affect growth
- Thyroid function: Both hypothyroidism and hyperthyroidism can disrupt hair growth
Diet plays a crucial role in hair health. Consuming adequate protein, vitamins, and minerals supports optimal growth. Hormonal imbalances, particularly those affecting thyroid function, can significantly impact hair growth cycles.
Stress, medications, and certain medical conditions may also influence hair growth patterns. Managing these factors can help maintain healthy hair growth and prevent premature hair loss or thinning.
Restoring Hair Health
Restoring hair health involves addressing underlying issues, exploring treatment options, and making lifestyle modifications. These approaches can help stimulate growth and improve overall hair condition.
Addressing Nutritional Deficiencies
A balanced diet plays a crucial role in hair health. Iron, zinc, biotin, and vitamins A, C, and D are essential for hair growth. Incorporating foods rich in these nutrients can help combat deficiencies.
Iron-rich foods include lean meats, spinach, and lentils. Eggs, nuts, and whole grains provide zinc and biotin. Citrus fruits offer vitamin C, while fatty fish and fortified dairy products supply vitamin D.
Supplements can fill nutritional gaps. Biotin supplements may be beneficial, but consult a healthcare provider before starting any new regimen. A blood test can identify specific deficiencies to target.
Medical and Natural Treatment Options
Minoxidil is an FDA-approved over-the-counter treatment for hair loss. It comes in liquid or foam form and is applied directly to the scalp. Finasteride (Propecia) is a prescription medication for male pattern baldness.
For female pattern hair loss (FPHL), dermatologists may recommend hormonal treatments or other specialized medications. Hair transplants are a surgical option for severe cases.
Natural remedies include rosemary oil and aloe vera. Scalp massages can improve blood circulation. These methods may complement medical treatments but shouldn’t replace professional advice.
Lifestyle and Haircare Modifications
Stress management is crucial for hair health. High stress levels increase cortisol production, which can disrupt the hair growth cycle. Regular exercise, meditation, and adequate sleep can help reduce stress.
Gentle haircare practices are essential. Avoid harsh chemicals and excessive heat styling. Use a mild shampoo and conditioner suitable for your hair type. Regular trims can prevent split ends and breakage.
Scalp health is vital. Keep the scalp clean and moisturized. Hair masks can provide extra nourishment. Protect hair from sun damage and chlorine when swimming. Be gentle when brushing or styling to minimize breakage.
Conclusion
Hair growth issues can stem from various factors like genetics, nutrition, hormones, and hair care practices. Addressing the root cause is crucial for restoring healthy growth. Consulting a dermatologist can provide personalized solutions and treatments. With proper care and patience, many people can improve their hair growth and overall hair health.
