Hi everyone,
Abstract
Hair relaxers are used by millions of black women, possibly exposing them to various chemicals through scalp lesions and burns. In the Black Women's Health Study, the authors assessed hair relaxer use in relation to uterine leiomyomata incidence. In 1997, participants reported on hairrelaxer use (age at first use, frequency, duration, number of burns, and type of formulation). From 1997 to 2009, 23,580 premenopausal women were followed for incident uterine leiomyomata. Multivariable Cox regression was used to estimate incidence rate ratios and 95% confidence intervals. During 199,991 person-years, 7,146 cases of uterine leiomyomata were reported as confirmed by ultrasound (n = 4,630) or surgery (n = 2,516). The incidence rate ratio comparing ever with never use of relaxers was 1.17 (95% confidence interval (CI): 1.06, 1.30). Positive trends were observed for frequency of use (P(trend) < 0.001), duration of use (P(trend) = 0.015), and number of burns (P(trend) < 0.001). Among long-term users (≥10 years), the incidence rate ratios for frequency of use categories 3-4, 5-6, and ≥7 versus 1-2 times/year were 1.04 (95% CI: 0.92, 1.19), 1.12 (95% CI: 0.99, 1.27), and 1.15 (95% CI: 1.01, 1.31), respectively (P(trend) = 0.002). Risk was unrelated to age at first use or type of formulation. These findings raise the hypothesis that hair relaxer use increases uterine leiomyomata risk.

ReplyDeleteTina i'm not sure if the study is complete... i am skeptical of research in general bc many of them have biases from the get-go. my questions are these: what was being controlled for in this research and were any other possible causes acknowledged and accounted for? I have had to do my share of research for school and any even remotely educated person knows that this hypothesis most likely is not the "be all and end all" aka the outright cause of fibroids. that being said, the article states that "Researchers fear that Black women are being exposed to chemicals that gain access into the body through lesions on the scalp by burn from even best hair relaxers." specifically what chemicals are being talked about and has it been proven that these chemicals correlate directly with fibroids after controlling for alternate explanations? this article also ***umes that every relaxer that is done results in burns/lesions, which isn't necessarily the case. how often were the relaxers done by those being studied and could that have an impact? i can already see the flaws and i haven't even read the study as yet. when these questions are answered and not blanketed in an article (such as this one) that seeks to deter women from doing what they want with the hair on their heads, and when (if at all) this hypothesis is proven, then i will reconsider bc my healthy def comes 1st and foremost. but until then, i will keep continue to do what i want with my hair and keep abreast of this "research."
ReplyDeleteHi Jamie, You raise some excellent points and I think that follow-up studies will address some of them. It's a start and I look forward to additional information. Thank you for your informed comments! Tina
ReplyDeleteFibroids within a woman's uterus aren't actually regarded as deadly, although, the uterine fibroid signs and symptoms e.g. pressure in internal organs, abnormal bleeding during menstruation etc. is often quite distressing. Even though menopausal processes usually shrink fibroids the natural way, there are actually a number of must try natural fibroid remedies designed for women who desire to be delivered from the frustrating symptoms caused by uterine fibroids.

Hi Kaney, Thanks so much for responding to this post.

Hey Gina! I saw your comment about Dr. Uduehi’s medication concerning Fibroid sometime ago and you were right, I tried it and it worked like magic for me. It was like hell living with FIBROID all this years until now, no more pains, bleeding and no miscarriage and I would've come with my testimony before now but I have to wait for a couple of months to see if it will regrow again but there's still no sign of fibroid, I also went to the hospital for test and still i was tested negative. All thanks to Dr. Uduehi and to you too Gina. And for anyone out there who wish to try can reach the doctor through: (+2347084878384) uduehiherbalcare@gmail.com
