Q. How does one get allergic to something?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Allergies develop when the immune system reacts in an exaggerated and abnormal way to substances that are typically harmless to most people. These substances, known as allergens, can include pollen, certain foods, animal dander, dust mites, insect venom, and more. The process of becoming allergic to something involves several steps:
Sensitization: The first exposure to an allergen usually doesn't cause an allergic reaction. Instead, it triggers the immune system to produce specific antibodies called immunoglobulin E (IgE). This process is known as sensitization. The immune system recognizes the allergen as a potential threat and starts producing IgE antibodies against it.
Activation of Mast Cells: After sensitization, subsequent exposures to the same allergen can lead to an allergic reaction. When allergens come into contact with IgE antibodies attached to immune cells called mast cells and basophils, these cells release inflammatory chemicals like histamine. These chemicals are responsible for the symptoms of an allergic reaction.
Allergic Reaction: The release of histamine and other inflammatory substances results in a range of symptoms that can affect the skin, respiratory system, gastrointestinal tract, and more. Common allergic reactions include itching, sneezing, runny nose, watery eyes, skin rashes, swelling, and in severe cases, anaphylaxis, which is a life-threatening reaction that requires immediate medical attention.
It's important to note that not everyone exposed to an allergen will develop an allergy. Genetic factors play a role in determining an individual's susceptibility to allergies. If you have a family history of allergies, you might be more likely to develop them yourself. Additionally, repeated and prolonged exposure to certain allergens can increase the likelihood of developing an allergy over time.
Allergies can emerge at any point in life, even if you haven't previously shown any sensitivity to a particular substance. Likewise, allergies can also change or fade over time. If you suspect you have developed allergies, consulting with a medical professional, such as an allergist or immunologist, can help you identify specific triggers, manage symptoms, and explore treatment options like antihistamines, nasal corticosteroids, or allergen immunotherapy (allergy shots).

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
