What helps against hair loss?
Hair loss is a normal part of the hair cycle and it is quite normal to lose some hair every day. On average, you lose around 50 to 100 hairs per day. This is normal and nothing to worry about as the hair is in a constant cycle of growth. In this article, we have summarised for you when hair loss is no longer normal (for example, diffuse hair loss), the various underlying causes and what you can do about it.
When hair loss is no longer normal?
The phenomenon is considered problematic when it is permanent and causes visible thinning or bald patches. Here are some signs that indicate that hair loss is no longer normal:
Sudden severe hair loss: If large amounts of hair suddenly fall out in a short period of time, this could indicate a health problem.
Permanent hair loss: If hair loss continues over a longer period of time without new hair growing back, this is a sign of an abnormality.
Visible thinning or bald patches: If the hair loss results in visible bald patches or a significant thinning of the hair volume, this is no longer considered normal. In this case, we speak of circular hair loss.
Hair loss at a young age: If severe hair loss occurs at a young age, especially before the age of 30, this is often a sign that something is wrong.
Accompanying symptoms: If the severe hair loss is accompanied by other symptoms, such as itching, dandruff, redness or pain on the scalp, this could indicate an infection or skin condition.
It's important to note that there can be many different causes, including genetics, changes in hormone production, psychological stress, diet and medical problems.
What can trigger hair loss?
Hair loss can be caused by a variety of factors and triggers. The exact cause can vary from person to person, and sometimes there are several factors that combine to cause severe hair loss. Here are some of the most common triggers:
Genetic predisposition: Heredity plays an important role. Androgenetic alopecia (male or female pattern hair loss), for example, is mainly caused by genetic factors.
Hormonal changes: Fluctuations in hormones can be the cause of diffuse or circular hair loss. This can occur during pregnancy, the menopause, when taking the pill or due to hormonal imbalances.
Medications: Some medications, such as chemotherapy, blood pressure medication, antidepressants and others, can also be the cause of sudden severe hair loss.
Diseases: Certain diseases, such as thyroid disorders, autoimmune diseases (e.g. alopecia areata), thyroid disease, alopecia areata and other diseases can cause hair loss.
Stress: Chronic emotional or physical stress can also trigger increased hair loss.
Nutrient deficiency: A lack of certain nutrients such as iron, vitamin D and proteins can slow down hair growth. Below we have summarised important information on the influence of certain vitamins and minerals on hair health.
Ageing: With age, the density and thickness of hair often decreases, the growth cycle shortens and hair falls out faster.
Mechanical stress: Excessive pulling of the hair due to tight hairstyles, such as braids or buns, can also be a reason for sudden hair loss.
Chemical treatments and heat: Excessive use of hair styling tools and chemical treatments such as bleaching or colouring can weaken the hair until it eventually falls out.
Environmental conditions: Factors such as strong sunlight and pollution can also damage the hair.
What are the different types of severe hair loss?
A distinction is made between different types depending on the cause, severity and duration:
Androgenetic alopecia (male and female pattern hair loss): This is the most common form of severe hair loss and affects both men and women and is a genetic and hormonal hair loss. In men, it leads to a gradual thinning of the hair on the scalp, often starting in the temples and the crown of the head. In women, it leads to diffuse thinning of the hair on the entire scalp.
Alopecia areata: This is an autoimmune disease in which the immune system attacks the hair follicles, resulting in round, bald patches on the scalp or other areas of the body. It is also often referred to synonymously as circular hair loss. Mostly women are affected.
Telogenous effluvium: This is a temporary phenomenon that is often caused by psychological stress, changes in hormone production, serious illnesses or certain medications. It is usually diffuse hair loss.
Anagen Effluvium: This is a sudden hair loss that is usually caused by chemotherapy or radiotherapy for the treatment of cancer. The hair falls out during the growth phase.
Traction alopecia: This is a mechanically induced hair loss caused by excessive pulling or tightening of the hair due to tight hairstyles, buns or plaits. As women usually style their hair more often, this type of hair loss is more common in women.
Cicatricial hair loss: This is a rare type of disease-related hair loss in which scar tissue replaces the hair follicles. This can occur due to infections, injuries or autoimmune diseases.
Hereditary hair loss: This hair loss occurs due to genetic predisposition and can occur in various patterns. One example is receding hairlines in men.
Diffuse hair loss: This refers to a uniform loss of hair over the entire scalp, which can be caused by various factors, including nutritional deficiencies, hormonal imbalances or medication. Although both men and women can be affected, diffuse hair loss is more common in women than in men.
Frontal Fibrosing Alopecia (FFA): This is a form of scarring hair loss that usually affects women and shifts the hairline backwards.
Why do some women experience hair loss after giving birth?
The phenomenon known as postpartum hair loss or postpartum hair loss is common. Postpartum hair loss occurs in the months after giving birth. There can be several causes:
Hormonal changes: During pregnancy, women experience an increase in certain hormones, such as oestrogen, which initially promote the growth of scalp hair. After giving birth, hormone levels drop rapidly, leading to a change in the hair cycle.
Transition to the telogen phase: Hair goes through different phases in the growth cycle, including the anagen phase (growth phase) and the telogen phase (resting phase). Pregnancy hormones prolong the anagen phase and reduce the telogen phase. After birth, however, the hair returns to the telogen phase and the hair that is in this phase is shed more.
Stress and lack of sleep: Childbirth can be stressful and sleep-robbing, which can increase hair loss. Stress can accelerate hair loss and lack of sleep can affect the regeneration of hair follicles.
Nutritional factors: During pregnancy, a healthy diet is often prioritised to ensure the well-being of the child. After birth, however, there may be changes in diet, which can affect hair health.
Until when does hair loss after childbirth last?
Hair loss after childbirth, known as postpartum hair loss, usually occurs in the first three to six months after giving birth. It is usually temporary and should subside within a period of three to six months. During this time, it is advisable to maintain a healthy diet, reduce stress, ensure adequate sleep and use gentle hair care practices.
Here are some tips to deal with postpartum hair loss:
- Maintain a balanced diet and make sure you are getting enough nutrients.
- Reduce stress and get enough sleep.
- Use gentle care products and avoid aggressive styling.
- Be patient, as hair usually grows back and recovers.
If hair loss persists or worsens after six months or if other unusual symptoms occur, it is advisable to consult a dermatologist or doctor.
Could a lack of certain nutrients also trigger hair loss?
Yes, a lack of various vitamins and minerals can also cause increased hair loss as a symptom:
Iron: A lack of iron can result in iron deficiency anaemia, which can cause hair loss. Iron is important for supplying the hair follicles with oxygen [1].
Vitamin D: A low vitamin D level can impair hair growth. It plays a role in the regulation of the hair cycle [2].
Biotin (also vitamin B7 vitamin H): Biotin is important for the health of skin, hair and nails. A biotin deficiency can lead to hair loss [3].
Vitamin A: An excess or deficiency of vitamin A can cause hair loss. The right balance is important [4].
Vitamin C: Vitamin C is important for the production of collagen, which strengthens hair, skin and nails and also for the metabolisation of iron [5].
Vitamin E: This antioxidant promotes blood circulation in the scalp and can support hair growth and thus protect against hair loss [6].
Zinc: A zinc deficiency can lead to sudden hair loss, as zinc is important for cell division and growth [7].
Proteins: Hair is mainly made up of protein, so an adequate protein intake is important. A protein deficiency can lead to brittle hair [8].
We have summarised more information on vitamins and nutrients that support hair health for you in this article.
However, it is important to note that hair loss is not always caused by a lack of nutrients. The exact cause should be diagnosed by a doctor or dermatologist. They can perform blood tests to determine deficiencies and recommend appropriate treatment or supplements.
What helps against hair loss?
The effectiveness of remedies and measures depends heavily on the cause. In some cases, it is not possible to completely stop or reverse hair loss, especially if it is genetic. However, there are various approaches and treatments that can help, depending on the cause. Here are some possible remedies:
Medication: In some cases, prescription medication or other remedies may be helpful. For example, minoxidil (as a topical solution or foam) is used to treat androgenetic alopecia. Finasteride is another medication that is often used for male pattern hair loss.
Hormone treatments: Hormone therapies can be considered for hormonal hair loss.
Nutritional optimisation: A lack of certain nutrients can also be a cause, as mentioned in the previous section. A balanced diet rich in iron, vitamins, minerals and proteins can promote the growth of scalp hair.
Stress management: Reducing stress can be helpful for hair loss caused by stress. Relaxation exercises such as yoga or meditation can be useful.
Scalp care: A healthy scalp is important for healthy hair. Using mild shampoos and balanced conditioners can support skin health.
However, it is important to note that there is no quick fix, and results may vary. Hair growth is a slow process, and most treatments require patience and continuity.
What specific home remedies can help with severe hair loss?
There are some home remedies that can help with promoting hair health, but it is important to note that natural remedies are not able to treat and stop all hair loss, especially if it is due to genetic factors or severe medical issues. Nevertheless, the following remedies can help promote hair health:
Coconut oil: Coconut oil contains fatty acids that can strengthen hair and protect it from breakage [9].
Aloe vera: Aloe vera gel can be applied to the scalp to soothe and condition it. It also has anti-inflammatory properties - after all, a stressed scalp can also be a trigger for severe hair loss [10].
Onion juice: Some studies suggest that onion juice - applied to the scalp - can promote hair growth. One study concluded that onion juice treatment for circular hair loss (alopecia areata) effectively stimulates hair growth [11].
Green tea: Green tea contains antioxidants and DHT (dihydrotestosterone) blockers, which can promote hair growth. DHT is a hormone that has been linked to hair loss [12].
Castor oil: Castor oil can help improve hair health. It is often used as a hair mask [13].
Which doctor should I see if I have severe hair loss?
If you are suffering from increased hair loss, it is advisable to see a dermatologist. A dermatologist is a doctor who specialises in skin, hair and nails and has the expertise to determine the exact cause and recommend appropriate treatment measures.
The dermatologist will carry out a thorough examination of the skin on your head and hair. In some cases, they may also order blood tests to identify possible deficiencies or underlying health problems that could be causing the hair loss. Depending on the cause, the dermatologist may suggest appropriate treatment options, which can range from medical therapies to lifestyle changes and hair care.
