Summer often brings concerns about increased hair shedding, and trichologist Tina Mui sheds light on this common issue, emphasizing that understanding the nuances of scalp health is crucial. Her insights reveal that while seasonal rhythms play a role, lifestyle factors and proper care are equally significant in maintaining vibrant hair. By focusing on both internal and external influences, we can proactively address hair concerns and ensure a healthy foundation for hair growth.
Understanding Seasonal Hair Loss and Optimal Scalp Care
Tina Mui, a distinguished trichologist and co-founder of AWARE Hair, recently provided expert commentary on the phenomenon of increased hair shedding during the warmer months. During an exclusive interview, Mui explained that while a scientific consensus on a direct causal link between summer heat and hair loss is still developing, practical observations indicate a strong correlation between summer activities, product usage, and perceived hair thinning.
Mui elucidated that the heightened production of sweat and oil on the scalp, a natural response to warmer temperatures, can lead to roots feeling weighed down. This effect is often compounded by the use of styling products, sunscreens, dry shampoos, and exposure to saltwater and chlorine, which can further diminish hair volume. She noted that clients frequently mistake this temporary flattening for actual density loss, only to find their hair regains its fullness after thorough cleansing and appropriate styling.
She underscored the critical importance of proactive scalp care, likening it to daily dental hygiene or sun protection. Mui advocated for regular scalp cleansing and nourishment, not merely as a reactive measure to issues like oiliness, irritation, or flakiness, but as an integral part of a preventative hair care regimen. She highlighted products like AWARE Hair 9·1 Professional Scalp Care Shampoo, designed to cleanse follicles effectively while supporting hair treatments and infusing the scalp with hydrating and antioxidant-rich ingredients.
Addressing the seasonal shedding pattern, Mui elaborated that hair typically follows a subtle rhythm, with a slightly higher percentage of hairs entering the resting (telogen) phase in summer, leading to noticeable shedding by late summer or early autumn. This biological response, she suggested, might be influenced by longer daylight hours, potentially reflecting an evolutionary remnant of seasonal molting observed in other mammals. Beyond natural cycles, summer environmental factors such as increased sun exposure, swimming, and frequent washing can weaken hair fibers and contribute to breakage.
For those considering scalp stimulation, Mui offered guidance on using tools like a gua sha. She stressed that the objective is to gently move the scalp skin, not to scrape it, using light to medium pressure. Her recommended technique involves dividing the scalp into four sections, gliding the tool from the hairline to the crown, performing gentle circles at the crown, and focusing on temples and the nape of the neck. She advised using the tool with conditioner or a scalp mask for enhanced slip, or simply utilizing fingertips to avoid scratching.
Mui emphasized that every hair follicle is a delicate mini-organ with its own blood supply. Sluggish circulation can impede optimal follicle function, making gentle scalp stimulation beneficial for encouraging blood flow and releasing fascial tension. The goal, she reiterated, is to manipulate the scalp tissue beneath the hair, not just the hair itself.
Regarding signs of an unhealthy scalp, Mui pointed out that shedding is often a late indicator. Persistent itching, redness, excessive oiliness, waxy buildup, unusual odor, recurring flakes, bumps, sores, or pain are earlier warnings. She urged individuals to observe changes in their scalp's behavior, especially if discomfort persists or their usual routine becomes ineffective. While shedding 50 to 100 hairs daily is normal, Mui advised attention to significant deviations, such as a noticeable reduction in ponytail thickness, a widening hair part, excessive hair in brushes or drains, or prolonged shedding beyond several weeks. Sudden bald patches or clumps of hair loss warrant immediate consultation with a dermatologist or medical professional, as underlying health issues like illness, surgery, stress, rapid weight loss, or hormonal shifts could be contributing factors that occurred several months prior.
