When Brian Plunkett ART MIT, a member of the Institute of Trichologists and Founder of Trichocare Diagnostics Limited started to see unsafe hair hygiene advice circulating in the food industry, he was concerned enough to put pen to paper and create a first, definitive Food, Hygiene and Hair guide.
The findings confirmed that there are many more aspects to hair hygiene control than the simplistic solution of fully encasing the hair, which some in the industry continue to advocate.
So, how does hair grow and fall?
At any given time, approximately 90% of human hair is growing. These hairs are at no normal risk of being shed. The remaining 10% that are resting do give some concern to hygiene critical environments.
Whilst it is factually correct that the human scalp may shed around 100 hairs per day, it is not the case that this occurs at a constant rate throughout the day. The majority of natural, daily human hair loss is predictable and occurs when hairs that are ready for shedding are agitated through grooming processes such as washing, brushing and drying.
For the most part hairs about to be shed remain stably attached to the scalp; they do not need overbearing coverings. This would be counter-productive and interfere with the natural temperature control of the head; leading to the wearer touching and adjusting headwear in the factory environment.
With this in mind, when double layering headwear, it is important that products work together to aid moisture transportation, otherwise overheating can occur, especially in warm environments.
Hairnets function to provide a breathable, precautionary restraint against the minority of hairs that can remain precariously attached to the scalp between those times when cleansing and brushing activities occur.
