German researchers investigated the role of a particular amino acid in hair loss and regrowth. They divided people with significant hair loss into two groups. One group just got a placebo. The second group received a treatment of millet seed extract, vitamin B5, and the amino acid l-cysteine. In just eight weeks, the lucky members of the treatment group stopped losing their hair – and saw it start to grow back.

Researchers asked women between the ages of 40 and 65 to attend two 90-minute, in-person training sessions on how to perform facial exercises. Then, they did the exercises at home every day for 30 minutes for eight weeks. After week eight, they did the exercises for 30 minutes every other day until the end of week 20. Dermatologists then assessed photos of the participants at the beginning of the study, at the end of week eight, and at the end of week 20. Their average age estimate went from 50.8 years to 49.6 years to 48.1 years as the study progressed. The participants agreed that the exercises made a difference and reported being highly satisfied with the results.

Researchers found that when people are sleep-deprived, their hormones shift. Levels of ghrelin, which signals hunger, increase, while satiety hormones decrease. Levels of appetite-stimulating endocannabinoids rise. And gut bacteria get out of balance. These changes encourage people to eat more food and more calorie-dense food, move less, and be more impulsive in their food choices.
