“…and bacterial load were correlated to the total dandruff scores and self‐reported itch, suggesting that the microbiota may play a role in both symptoms. These findings are consistent with previous reports on Asian populations 13 . In a 2‐week study of an Asian population aged 18–75 years, low frequency of shampooing was associated with an increase in flakes, itchiness, and a 2–3‐fold increase in the Malassezia spp.…”

“…12 Washing Afro hair can be a lengthy and extensive process due to the specific need to detangle the hair 3 and the long drying time of the hair and scalp, compared with Caucasian women who typically wash their hair every other day. 13 When investigating self-assessment in a cohort of 727 Nigerian women in a study examining the effect of haircare practices on common scalp complaints, the participants declared that their hair care routines contributed to major scalp symptoms such as hair loss (40%) itching (34%), and flaking or scaling (24%), which are two symptoms related to the creation of dandruff. 14 Also, a study assessing the incidence of dandruff in different ethnicities found higher dandruff prevalence in women of African American descent (81%-95%), than in other ethnic groups, with 66%-82% and 30%-42% prevalence for women of Caucasian and Asian descent, respectively.…”

Dandruff and scalp discomfort are common concerns for women and men in Africa. Moreover, women with afro‐textured hair are prone to scalp discomfort owing to irregular hair washing, frequent use of oil‐based products on their scalp, and harsh chemical treatments. Current literature does not, however, provide data on the pathophysiological mechanisms of these conditions in this population. In this study, we investigated the mechanisms behind scalp discomfort and dandruff in women of African descent before and after hair washing. We conducted the in Durban, South Africa, over a 3‐week period with 60 women of African descent aged 20–40 years. The respondents were equally divided into a “dandruff” and a “no dandruff” group, based on clinical grading of adherent dandruff by a dermatologist. Malassezia spp. and bacterial loads were quantified by quantitative polymerase chain reaction. Evaluations of scalp condition and sample collection were performed at five time points during the 3 weeks. Data on discomfort symptoms were collected via a self‐assessment questionnaire. We observed that the dandruff severity peaked at the end of the first week after hair washing and plateaued from thereon in both groups. Dandruff was associated with higher Malassezia and bacterial load counts and there was a direct correlation between the Malassezia spp. load and dandruff score. Via self‐assessment questionnaire responses submitted by participants, we observed that itching was the most pronounced scalp discomfort, compared with the sensation of tingling and burning at baseline, while an improvement of the scalp symptoms of dandruff and itch was observed in both groups after one hair wash. The study also showed that higher colonization with Malassezia spp. and bacteria is associated with dandruff independently of the time point, confirming a scalp microbiome contribution to the dandruff pathophysiology in the study population. The benefits of washing were, however, not sustained after 1 week and we thus recommend weekly hair washing for long‐term management of dandruff and scalp itchiness in this population.

“…Sedangkan faktor eksternal yang dapat mempengaruhi kondisi kesehatan rambut, yakni penggunaan hijab/penutup kepala pada wanita, catok dan blowdry, mengikat rambut terlalu kuat dan tindakan perawatan rambut yang berlebihan. ( 7) Dalam Studi Epidemiologi, peningkatan frekuensi keramas berpengaruh terhadap berkurangnya pengelupasan seperti gatal dan kulit kepala yang kering (8). Hasil uji statistik chi-square pada frekuensi keramas dalam seminggu diperoleh nilai p sebesar 0,025 (p<0,05) yang berarti terdapat hubungan antara frekuensi keramas dalam seminggu terhadap kondisi kesehatan rambut.…”

Penggunaan hijab yang tidak diikuti dengan perawatan rambut yang rutin dan tepat dapat memicu terjadinya permasalahan rambut. Peningkatan frekuensi keramas berpengaruh terhadap berkurangnya pengelupasan seperti gatal dan kulit kepala yang kering. Kesehatan rambut adalah kondisi pada kulit kepala dan rambut yang ditandai dengan tidak terdapatnya keluhan yang mengganggu pada kulit kepala dan rambut seperti ketombe, rontok, tidak kering, tidak kusam, tidak berminyak, dan mudah ditata. Untuk mengetahui pengaruh penggunaan hijab dan frekuensi keramas terhadap kondisi kesehatan rambut. Jenis penelitian analitik observasi dengan pendekatan cross sectional. Analisis data menggunakan uji chi-square. Sampel penelitian ini sebanyak 134 responden dari Mahasiswi Fakultas Kedokteran Universitas Muslim Indonesia Angkatan 2021 dengan menggunakan teknik simple random sampling. Hasil penelitian ini menunjukkan bahwa penggunaan hijab menyerap keringat (p=0,031), penggunaan bahan hijab katun, sifon, polyester (p=0,027), berhijab dalam kondisi rambut basah (p=0,036), berhijab lebih dari 12 jam per hari (p=0,042), memakai dalaman jilbab yang lembut dan menyerap keringat (p=0,035), memakai bahan dalaman jilbab kaos dan spandex (p=0,044), frekuensi keramas dalam seminggu (p=0,025), mencuci rambut dengan sampo (p=0,005), menggunakan conditioner saat keramas (p=0,037) berpengaruh terhadap kondisi kesehatan rambut. Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa terdapat hubungan yang signifikan antara penggunaan hijab dan frekuensi keramas terhadap kondisi kesehatan rambut. Bagi peneliti selanjutnya, perlu kiranya melakukan penelitian lanjutan dengan faktor-faktor lain yang dapat memberikan pengaruh yang signifikan terhadap kesehatan kulit kepala dan rambut.
