Q & A
Does cutting your hair make it grow faster?
-No, cutting your hair does not make it grow faster. Hair grows around half an inch per month regardless of trimming.
What causes dandruff, and is it related to having a dry scalp?
-Dandruff is not caused by a dry scalp; it is typically caused by an overgrowth of the Malassezia yeast, which thrives on oily scalps.
Does shampooing your hair every day cause hair loss?
-No, shampooing does not cause hair loss. It helps dislodge hairs that were already ready to fall out.
Does shaving cause hair to grow back thicker and darker?
-No, shaving does not make hair grow back thicker or darker. It only makes the hair ends blunt, which can give the appearance of being thicker.
Is air-drying your hair always better than blow-drying?
-Not necessarily. Both methods can be damaging if done improperly. It's important to use the correct technique for each method.
Can you repair split ends without cutting them?
-No, once a split end occurs, the only way to repair it is to cut it off.
Is baldness only inherited from your mother?
-No, baldness can be inherited from either your mother's or father's side of the family.
Does brushing your hair more often make it healthier?
-Overbrushing can cause microtears along the hair shaft and potentially damage your hair. Gentle detangling is recommended.
Do oils make hair grow faster and longer?
-No, oils do not make hair grow faster or longer. Eating a diet with enough oils is important for scalp health, but applying oils to the scalp does not stimulate hair growth.
Are wigs, weaves, and braids always protective for your hair?
-Not always. They can cause damage if they are too tight, too heavy, or if the scalp is neglected while wearing them.
Does stress cause gray hair?
-Stress can speed up the graying process, but when you go gray is largely determined by genetics.
Can waxing cause ingrown hairs?
-Yes, any hair removal method that breaks the hair instead of pulling it out from the root can cause ingrown hairs.

π Debunking Hair Care Myths
This paragraph delves into common hair care misconceptions with the help of Anabel Kingsley, a trichologist, and Dr. Howard, a dermatologist. They clarify that hair growth rate is constant and not affected by cutting, and that dandruff is caused by an oily scalp due to the Malassezia yeast, not dryness. The paragraph also addresses the myth of hair loss from shampooing, explaining that it only removes loose hairs, and the misconception that washing daily is harmful. Instead, it emphasizes the importance of scalp health for hair growth and the need for proper cleansing and hydration. Additionally, it dispels the myth that shaving makes hair grow back thicker and darker, highlighting the natural tapering of hair and the appearance of thickness post-shave.
πΏ Hair Washing and Care Techniques
This section discusses the appropriate methods for hair care, including washing and drying. It refutes the myth that air-drying is always better than blow-drying, stating that the method's impact depends on how it's done. For instance, air-drying with constant tugging can be damaging, while blow-drying with a heat-protectant and proper technique can be less harmful. The paragraph also addresses the myth of shampooing causing hair loss, explaining that it merely dislodges hairs already in the shedding phase. It advises focusing on scalp health during shampooing and mentions the causes and treatments for ingrown hairs, as well as the role of stress and genetics in hair graying.
π΅ Hair Loss, Graying, and Care Tips
This paragraph explores various hair-related myths and facts. It starts by dispelling the myth that plucking a gray hair results in two more, emphasizing that hair graying is genetic but can be accelerated by stress. It also addresses the impossibility of repairing split ends, explaining that they are a result of daily wear and tear and can only be resolved by trimming. The paragraph discusses the genetic aspects of baldness, including the roles of both parents and hormonal influences. It also warns against over-brushing, which can cause microtears in the hair, and instead recommends using brushes with rounded plastic prongs and a vented cushion base. Lastly, it touches on the myth of oils promoting hair growth, clarifying that while dietary oils are important, topical application does not accelerate growth.

Highlights
Hair grows at a consistent rate of half an inch per month, and cutting it does not speed up the process.
On average, there are 120,000 hair follicles on the human scalp, each going through different phases of the hair-growth cycle.
Dandruff is not caused by dry scalp but is actually due to an overgrowth of yeast that thrives in oily conditions.
Seborrheic dermatitis, or dandruff, is associated with the Malassezia yeast which is lipophilic and feeds on sebum.
Daily shampooing is not harmful; it's essential for proper scalp cleansing and hydration, especially for different hair types.
Shaving hair does not cause it to grow back thicker or darker; it only appears that way due to the blunt ends created by shaving.
Air-drying and blow-drying can both be damaging depending on the method used; gentle handling and proper technique are key.
Shampooing does not cause extra hair loss; it merely dislodges hairs that were already loose and ready to fall out.
Ingrown hairs can occur with any hair-removal method that breaks the hair instead of pulling it out from the root.
Stress can accelerate the process of hair graying, which is largely determined by genetics and the production of melanin pigment cells.
Plucking a gray hair does not cause two more to grow in its place; it's a myth without scientific evidence.
Split ends cannot be repaired; they are a result of daily wear and tear and require trimming to be removed.
Baldness or hair loss can be inherited from either the mother's or father's side and is influenced by hormone levels.
Overbrushing can cause microtears in the hair shaft and is especially damaging to textured or coily hair.
Oils do not make hair grow faster or longer, and applying pure oil to the scalp is not recommended.
Wigs, weaves, and braids do not always protect hair; they can cause breakage if too tight or worn for extended periods without proper care.
The term 'tender headed' may indicate scalp sensitivity or inflammation and should not be dismissed without proper attention.
