They were asked to look back and identify periods of extreme stress during the last year. But when the participants reported a reduction in stress, like going on vacation or resolving the tense event, the hair regained its pigment. Once the hair grows out of the scalp, it doesn't change color. It's just the new growth at the root that can. The stress response evolved to help humans survive danger. Today, a nasty email, a controlling boss or an unhappy marriage can elicit the same reaction.
Hair growth demands lots of energy and while strands are growing, cells receive signals from the body, including stress hormones, the authors write.
Hair needs to reach a threshold before it turns gray, Picard said. If strands are about to go gray anyway — perhaps near middle age — a stressful event might push hair cells past that threshold earlier, the study noted. Then when the stress ends and the hair is just above the threshold, it could revert back to dark.
Some people start seeing gray hairs in their 20s; others in their 50s, so that window of opportunity will vary. The volunteers were also asked to keep a stress diary, rating each week's level of stress. Researchers noticed that some gray hairs regained their color, and tied the change to reduced stress, which they believe has to do with the mind-mitochondria connection.
There is no guarantee, however, that reducing stress will restore hair color—especially for those who have been gray for a long time. In middle age, when the hair is near that threshold because of biological age and other factors, stress will push it over the threshold and it transitions to gray," Picard continued.
Researchers believe they have made an important discovery to help stop one of the signs of aging. You may use them to reverse premature grey hair by grinding them into a powder and combining them with coconut oil to apply to your scalp.
One of the most effective remedies for stopping grey hair is makhan, yes, butter! Ridge gourd is well-known for its capacity to repair pigment cells in hair follicles, therefore reversing grey hair. Sun-dry one ridge guard, boil it in coconut oil and keep it in sun for four to five days before using it.
Onion juice remedy is probably the most frequently recommended tip on the internet. Imbalances in hydrogen peroxide lead to premature greying of hair. When we use onion juice, this hydrogen peroxide can neutralise the catalase enzyme found in onions which helps revere premature grey hair.
So mix onion juice with one tablespoon of lemon zest and watch the wonders it does for your grey hair. Use black tea along with a herbal conditioner as it has tannic acid which helps darken your hair. However, do not use shampoo after this because it may cause drying of the hair. You can shampoo your hair the next day.
