Hair loss is a common concern that affects millions of people worldwide. With so much information available, it’s easy to fall prey to myths and misconceptions about hair health. In this article, we’ll debunk some of the most common hair loss myths and provide expert insights from trichologists and dermatologists to help you better understand your hair and scalp.

Myth 1: Hair Grows Faster When You Constantly Cut It

Fact: Hair grows at an average rate of half an inch per month, and cutting it does not speed up this process.

Hair growth occurs in cycles: anagen (growth phase), catagen (transition phase), telogen (resting phase), and exogen (shedding phase). Cutting your hair simply removes split ends and makes it look healthier, but it doesn’t affect the growth rate. Regular trims are great for maintaining hair appearance, but they won’t make it grow faster.

Myth 2: Dandruff Is Caused by a Dry Scalp

Fact: Dandruff is almost always caused by an oily scalp, not dryness.

Dandruff, also known as seborrheic dermatitis, is linked to an overgrowth of Malassezia yeast, which thrives on oil. The more oil on your scalp, the more flakes you’ll see. Dandruff can appear on the scalp, behind the ears, or even on the sides of the nose. To treat it, use targeted shampoos, scalp toners, and masks, and consider adjusting your diet to reduce oil production.

Myth 3: Shampooing Causes Extra Hair Loss

Fact: Shampooing only dislodges hairs that are already loose and ready to shed.

It’s normal to lose up to 100 hairs a day. Shampooing helps maintain a healthy scalp by removing dirt, oil, and product buildup. A healthy scalp is essential for supporting new hair growth. Focus on cleansing your scalp thoroughly, and let the suds run through the lengths of your hair to keep them clean without over-manipulation.

Myth 4: Shaving Makes Hair Grow Back Thicker and Darker

Fact: Shaving only creates a blunt edge, making hair appear thicker temporarily.

Hair naturally grows tapered, and shaving doesn’t change its texture or color. If shaving truly made hair grow back thicker, many people would shave their heads regularly! Waxing, on the other hand, removes hair from the root, but it still grows back with its natural taper.

Myth 5: Air Drying Is Always Better Than Blow Drying

Fact: Both methods have pros and cons, depending on how you use them.

Air drying can be damaging if you roughly towel-dry or leave your hair wet for too long, which can lead to mold or mildew in braids or weaves. Blow drying, when done correctly, isn’t harmful. Use a heat protectant, hold the dryer at least six inches away, and start with medium heat before switching to low. For curly or coily hair, a hooded dryer may be a better option.

Myth 6: Stress Causes Gray Hair

Fact: Gray hair is primarily determined by genetics, but stress can accelerate the process.

Hair color is determined by melanin, a pigment produced by hair follicles. When these follicles stop producing melanin, hair turns gray. While stress can speed up graying, embracing your natural hair color or using dyes are both great options. Plucking gray hairs won’t cause more to grow back, but it can damage follicles over time.

Myth 7: You Can Repair Split Ends

Fact: Once a hair strand splits, it cannot be repaired.

Split ends result from daily wear and tear, such as brushing, blow drying, and exposure to UV rays. The only solution is to trim them. Treat your hair gently, like your favorite cashmere sweater, to prevent split ends in the first place.

Myth 8: Baldness Is Only Inherited from Your Mother’s Side

Fact: Hair loss can be inherited from either parent or even grandparents.

Androgenic alopecia, or hereditary hair loss, is influenced by genetics and hormone levels. Factors like menopause, pregnancy, or conditions like polycystic ovary syndrome (PCOS) can also impact hair density. Consult a trichologist or dermatologist for personalized treatment options.

Myth 9: The More You Brush Your Hair, the Healthier It Will Be

Fact: Over-brushing can cause micro-tears and damage, especially for textured or coily hair.

Detangling is important, but excessive brushing can harm your hair. Use a brush with rounded plastic prongs and a vented cushion base. For curly or coily hair, consider finger detangling or using specialized brushes like the Felicia Leatherwood or Denman brush.

Myth 10: Oils Make Hair Grow Faster and Longer

Fact: Oils do not directly promote hair growth, but they can improve scalp health and hair appearance.

While applying oils to your hair won’t make it grow faster, consuming healthy fats in your diet can support overall hair health. Instead of using pure oils on your scalp, opt for creams or products containing oils like olive, castor, or coconut for added moisture and shine.

Myth 11: Wigs, Weaves, and Braids Always Protect Your Hair

Fact: Protective styling can help, but it must be done responsibly.

Tight braids, heavy weaves, or neglecting your scalp can lead to breakage and hair loss. Practice “responsible protective styling” by ensuring your scalp is clean, hydrated, and free from tension. Avoid styles that cause pain or tenderness, as this could indicate inflammation or damage.

Myth 12: Tenderheadedness Is Normal

Fact: Scalp tenderness can be a sign of underlying issues like inflammation or scarring alopecia.

If your scalp is consistently tender, don’t dismiss it as normal. Consult a trichologist or dermatologist to rule out conditions like scarring alopecia. Early detection and treatment can prevent further damage.
