Hair loss is a common concern that can affect people year-round, with seasonal fluctuations often adding to the worry. While it’s normal to lose between 100 and 150 hairs daily, understanding when hair loss becomes a cause for concern is crucial.
When Should You Worry?
Dr. Miguel Sánchez Viera, director of the Instituto de Dermatología Integral, explains that increased shedding during hair washing or brushing is often a sign of temporary hair loss, known as telogen effluvium. This type of hair loss is typically triggered by stress, pregnancy, or hormonal changes and usually resolves on its own without treatment.
However, if you experience excessive and sustained hair loss or noticeable thinning, consulting a dermatologist is recommended. Dr. Eduardo López Bran, director of Imema and head of dermatology at Hospital Clínico San Carlos, advises that hair loss persisting for two to four months, accompanied by a decrease in hair density, a lighter scalp, or weaker hair, warrants a visit to a specialist. These signs could indicate underlying conditions requiring professional evaluation.
Daily Hair Washing and Hair Loss
The experts consulted for this article agree that washing your hair does not cause more hair loss. Dr. Viera emphasizes that washing should be tailored to individual needs, with no harm in washing twice a day, even after exercise. Dr. López Bran adds that neglecting scalp hygiene can actually be detrimental, leading to a buildup of oil, flakes, and product residue, ultimately harming hair health. While washing doesn’t contribute to hair loss, it can make normal shedding more noticeable. The traction from washing and brushing dislodges hair that is already in the process of falling out, making it appear as if you are losing more hair.
Nutritional Factors and Hair Loss
Deficiencies in certain vitamins and trace elements can contribute to hair loss. Cristina Morante, medical director of hair health clinic MC360, highlights the importance of iron, folic acid, biotin, vitamin D, magnesium, and zinc for maintaining healthy hair. Ensuring adequate intake of these nutrients is essential for preventing hair loss related to nutritional deficiencies.
Harmful Hair Products and Heat Styling
Parabens, ammonia dyes, and heat tools can weaken hair structure, making it brittle and fragile. These products are particularly detrimental when dealing with hair loss, as they can amplify the appearance of thinning. It’s recommended to minimize exposure to these culprits to promote healthy hair growth.
Diet and Hair Loss
While there are no miracle foods or supplements, maintaining a balanced diet is crucial for hair health. Dr. Sánchez Viera emphasizes the importance of consuming iron-rich foods like red meat, vegetables, and bones, as well as zinc-rich sources like meat and fish. These nutrients are essential for hair growth. Additionally, incorporating vitamins A and B into your diet is vital. Avoiding a diet high in carbohydrates, sugars, salt, and fats is recommended as these can weaken hair and contribute to thinning or brittleness.
Biotin’s Role in Hair Health
Pharmacist Helena Rodero highlights the importance of biotin for cell multiplication, a process crucial for healthy hair and nails. Biotin can be obtained from food and gut microbiota, but stress and certain medications can disrupt its absorption. In such cases, biotin or vitamin B8 supplements can be beneficial.
Anti-Hair Loss Products
Anti-hair loss products can extend the anagen (growth) phase of hair and delay the resting and shedding phases. Minoxidil is one of the most effective treatments for hair loss. Cristina de Hoyos explains that it acts as both a preventative and active treatment for hair loss, promoting follicle entry into the growth phase and slowing or stopping hair loss. Minoxidil should be applied daily to the scalp with a gentle massage for proper absorption. Women should avoid contact with other areas of the face as it can stimulate unwanted hair growth.
Remember, if you are experiencing significant or persistent hair loss, it’s essential to consult with a dermatologist for proper diagnosis and treatment recommendations.
