Hair loss can be caused by a variety of underlying factors, including poor diet, mineral deficiencies, medication use, stress or severe illness, environmental pollution, and genetic predisposition. Up to one-third of the population experiences hair loss, with thousands of women affected. While there’s no guarantee you can prevent hair loss determined by genetics or factors beyond your control, you can take steps to maintain healthy hair and delay its thinning.
Steps
Avoid Damaging Your Hair
Limit the use of hair dryers. Heat weakens the protein in your hair. Frequent use of heat to dry your hair can lead to brittle, weak strands that are more prone to falling out. Air-drying is the healthiest option for your hair, so try to let it dry naturally instead of relying on heat.
- Other heat-styling tools like curling irons, hot combs, and straighteners have similar effects.
- If you must use heat tools, be cautious, as continuous scalp heating can permanently damage hair follicles!
Avoid perming or straightening your hair. Chemical treatments like perming and straightening can damage your hair. These processes break the internal bonds of your hair and reshape it to either straighten or curl. This weakens the hair, leaving it dull, dry, and brittle. Over time, dry and brittle hair can contribute to hair loss.
Reduce chemical hair dye usage. Frequent use of chemical hair dyes increases the risk of significant hair damage. Avoid dyeing your hair more than once every four to six weeks. If your hair starts to gray, consider embracing the salt-and-pepper look instead of dyeing, as it’s healthier for your hair.
Avoid bleaching your hair. Bleaching strips away your hair’s natural pigment by allowing chemicals to penetrate the hair cuticle. This alters the hair’s structure and makes it more vulnerable to damage. Bleaching weakens your hair, and combining it with heat styling can cause further harm.
Avoid pulling your hair too tightly. Certain hairstyles that require tight pulling, such as ponytails, braids, cornrows, or dreadlocks, can lead to hair loss if worn daily. Tightly wound hairstyles, especially those using hot rollers, can also contribute to hair loss.
- "Traction alopecia" refers to hair loss caused by tight hairstyling. This condition is entirely preventable, as the cause lies in the styling itself!
Actively care for your hair
Wash your hair with a gentle shampoo. Hair loss can be prevented by regular washing, as it cleanses the hair and scalp (reducing the risk of infections that may cause hair loss). Avoid washing daily, as shampoo can strip away natural oils—washing every other day is ideal. Using a mild shampoo leaves your hair looking fuller and more voluminous compared to dirty hair, which tends to clump together.
Choose a shampoo that suits your hair type. A good shampoo promotes healthy hair, so take the time to find one that matches your hair type. Consider whether your hair is fine, dry, oily, or normal, and experiment with different shampoos to find the most effective one. If you have dandruff or color-treated hair, opt for shampoos specifically designed for those needs.
- Protein-enriched shampoos and conditioners can temporarily make hair feel thicker and fuller by filling gaps in the hair shaft, but they do not repair damaged hair.
Check ingredients for a gentle shampoo. Using a mild shampoo helps maintain a healthy scalp and hair. Reviewing the ingredients on the bottle can help determine if it’s gentle. Avoid shampoos containing sulfates, parabens, and/or sulfonates. Instead, look for those with isethionate or glucoside as the second ingredient after water.
- Common ingredients in gentle shampoos include sulfosuccinates, sultaines, and amphodiacetates.
- Silicones, polyquaterniums, and “guar” ingredients can be beneficial for hair conditioning.
Use a high-quality comb. How you comb your hair significantly impacts its health. Opt for a soft comb made from natural fibers, and avoid combing from the top down—start from the ends and work your way up. Be as gentle as possible and avoid pulling too hard.
- It’s best to avoid using brush-style combs on wet hair; stick to wide-tooth combs instead.
Try scalp massages. Massaging your scalp with nourishing oils (like coconut, rosemary, lavender, or almond oil) boosts blood circulation to the scalp and hair follicles. Rubbing and massaging the scalp warms the skin and increases blood flow, ensuring hair follicles receive more nutrients, which promotes optimal hair growth.
- Scalp massages also help you relax and benefit overall body function.
Test for hair loss if you're concerned. A common method to check for hair loss is the "pull test." Take a small section of hair (about 20-30 strands) between your thumb and index finger and gently pull. If more than 6 strands come out at once, it may indicate a hair loss issue.
- This is not a scientifically proven test, so consult a doctor or hair specialist if you suspect excessive hair loss. Remember, losing some hair daily is normal.
Eat Right for Healthy Hair
Maintain a balanced diet. A nutritious diet is a simple and effective way to prevent hair loss while promoting healthy hair, scalp, and overall well-being. A healthy body is more likely to support strong hair than a weak one. Hair loss can be slowed with a diet rich in vegetables and fruits. Specific vitamins and minerals (listed in the following steps) can strengthen hair and reduce hair loss.
Increase your iron intake. Iron is an essential mineral, available as heme iron from animal sources and non-heme iron from plant sources. Iron deficiency can lead to anemia, disrupting nutrient supply to hair follicles and increasing hair loss. To prevent this, include iron-rich foods in your diet.
- Red meat, poultry, and fish are excellent sources of iron.
- Leafy greens like broccoli, spinach, and kale are also rich in iron.
Consume enough protein. Protein is vital for healthy hair. A lack of protein can result in dry, weak hair and eventual hair loss. Adequate protein provides amino acids that strengthen hair. While protein is often found in shampoos, dietary protein improves hair health and prevents hair loss when consumed in sufficient amounts.
- Get protein from seafood, poultry, dairy, cheese, yogurt, eggs, beans, pork tenderloin, soy, lean beef, and protein bars.
- Vegetarians, vegans, and others can obtain plant-based protein from soy products, tofu, whole-grain bread, peanut butter, brown rice, lentils, quinoa, nuts, seitan, legumes, and broccoli.
Increase your vitamin C intake. Foods rich in vitamin C enhance iron absorption, so pair iron-rich foods with vitamin C sources for maximum benefits. Vitamin C also aids collagen production, strengthening capillaries that supply nutrients to hair shafts. Excellent sources of vitamin C include:
- Citrus fruits, kale, broccoli, Brussels sprouts, baked potatoes, and tomatoes.
- Blueberries, raspberries, and strawberries are also rich in vitamin C.
Ensure adequate Omega-3 fatty acids. These fats promote healthy hair and prevent dryness and brittleness. Found in scalp cells, they help moisturize hair and scalp. Omega-3s are essential fats the body cannot produce, so they must be obtained through diet.
- Include Omega-3-rich fish like tuna, salmon, and mackerel in your meals.
- You can also get Omega-3s from seeds and nuts, especially flaxseeds, pumpkin seeds, and walnuts.
Consume biotin-rich foods. Biotin, a water-soluble B vitamin, is crucial for hair health. A deficiency can lead to brittle hair and hair loss. Sources of biotin include whole grains, liver, egg whites, soy flour, walnuts, and brewer’s yeast.
- Whole grains also provide zinc, and zinc deficiency can cause a dry, itchy scalp and hair loss.
Consider dietary supplements. Consult your doctor before starting supplements, but options like biotin, inositol, iron, vitamin C, and saw palmetto may help prevent hair loss. While their effectiveness isn’t fully proven, anecdotal evidence suggests benefits.
Know which foods to avoid. Alongside knowing what to eat, it’s important to avoid certain foods. A balanced diet is key, but some items contribute to hair loss. Artificial sweeteners like aspartame are linked to thinning hair, and food additives can have negative effects.
- Raw egg whites contain a substance that binds to biotin, blocking its absorption.
Ensure sufficient calorie intake. A low-calorie diet can lead to temporary hair loss. The body requires vitamins and minerals (as listed above) to build and maintain hair. Reducing food intake can result in deficiencies of essential nutrients. Additionally, excessive calorie restriction can cause significant stress, leading to halted hair growth or a dormant phase. Avoid crash diets, or you may notice your hair thinning as you lose weight.
Seek Medical Help for Hair Loss
Know when to consult a doctor. It’s crucial to recognize when hair loss might indicate a more serious health issue requiring medical attention. Contact a doctor if you experience unusual hair loss, rapid thinning at a young age (under 20 or 30), or other concerning symptoms such as:
- Pain or itching accompanied by hair loss, or a red, scaly scalp.
- Bald patches in the beard or eyebrows.
- Women showing male-pattern baldness, abnormal facial or body hair growth, or irregular menstrual cycles, which may indicate hormonal imbalances.
- Weight gain, fatigue, muscle weakness, or cold intolerance.
Prepare for your doctor’s appointment. Before visiting a doctor, reflect on your symptoms to provide a clear description—when the hair loss began and whether it occurs in patches or continuously. Also, consider:
- Have you noticed poor hair growth, breakage, or shedding?
- Is there a family history of hair loss?
- Are you taking any medications or supplements?
Treatment options for men. Hereditary baldness is the most common cause of hair loss in men, typically characterized by a receding hairline forming an M shape. While not a disease and genetically influenced, treatments are available. Two common medications include:
- Minoxidil (Rogaine), a topical solution applied to the scalp to stimulate hair follicles, available in 2% and 5% strengths for daily use.
- Finasteride (Propecia, Proscar), an oral medication that interferes with testosterone production linked to baldness. Women of childbearing age should avoid handling this medication.
Treatment options for women. About one-third of women experience some degree of hair loss. Two-thirds of postmenopausal women deal with thinning or patchy hair loss. Women rarely experience frontal baldness but often notice thinning along the part line, spreading to the crown. Some treatments for female hair loss include:
- Minoxidil (Rogaine), applied topically and massaged into the scalp. Minoxidil is excreted in breast milk, so it should be avoided while breastfeeding.
- Anti-androgens, rarely prescribed, are medications that inhibit androgen effects.
- Iron supplements are prescribed for some women, particularly vegetarians, those with a history of anemia, or those with heavy menstrual bleeding.
Tips
- Avoid prolonged sun exposure for your hair.
- Steer clear of heat-styling tools as they damage hair, leading to split ends and breakage.
- Braiding hair before bed is better than leaving it loose, as it reduces tension during sleep.
- Avoid gels and similar products, as they often cause hair to become brittle, break, and damage easily.
- Opt for gentle shampoos and conditioners; they are milder and provide comprehensive hair care. Avoid harsh soaps, especially deodorant types, as they harm the scalp.
- Celiac disease can cause hair loss; consult a doctor if you’re concerned.
- It’s normal to lose about 100 hairs daily. Many hairs don’t shed until you shower. Be mindful if shedding increases, even without visible bald patches.
- Certain illnesses (like thyroid disorders) and antibiotic use can lead to hair loss, so maintaining good health helps mitigate these effects.
- During pregnancy, don’t panic if you experience postpartum hair loss. It’s a natural result of hormonal changes and typically resolves within months.
Warnings
- Hair loss can signal illness or poor health. Consult a doctor if concerned, especially with a poor diet, weakened immune system, or general unwellness.
