Hair growth occurs in three stages: the growth phase where the hair grows for around 2-7 years, the transition phase where the follicle starts to shrink and hair growth slows for around 2-3 weeks, and the resting phase where the hair falls out at the end of this phase at around 3- 4 months. The falling out of the hair strand is necessary so that a new strand can take its place, and the cycle can begin again.</p> Fri, 08 Nov 2024 15:56:16 +0000 Daniela Padres 10152 at /oss /oss/article/critical-thinking-health-and-nutrition-pseudoscience/are-fums-essential-oils-safe-inhale <p>“It’s like some… like a wooden cigarette that gives you flavours, but it’s not even a cigarette, you don’t even light it.”</p> Fri, 01 Nov 2024 06:09:08 +0000 Jonathan Jarry M.Sc. 10138 at /oss /oss/article/critical-thinking-student-contributors-health-and-nutrition/instant-coffee-and-acrylamide-should-you-be-worried <p>Coffee is a staple beverage for millions of people worldwide, consumed in endless scenarios: catching up with a friend, powering through an intense study session, or simply kickstarting the day.</p> <p>From the classic drip coffee and trendy cold brew to the precision of the French press and the intensity of espresso, there are countless ways to make the perfect cup of joe.

There is really nothing all that noteworthy here except for the official classification.

Such studies usually depend on participants filling out questionnaires about the amounts of specific foods consumed as well as the frequency of consumption. This is problematic because of faulty recall, inability to estimate amounts, and a tendency to report what the subject thinks should have been eaten as opposed to what was actually consumed.</p> Wed, 07 Aug 2024 14:25:36 +0000 Joe Schwarcz PhD 10019 at /oss
