"Castor oil will not grow hair," says cosmetic chemist and author Perry Romanowski matter-of-factly. "There is no evidence for it and no scientific theory supporting that it would work, so yes, it's a total myth." In better news, he says that castor oil is not damaging to the hair and can provide some conditioning that improves the flexibility of the hair fiber.
Castor oil, as some might already know, is one of the most popular all-natural "panaceas." Go ahead, Google it: What you'll find is article after article about how the viscous oil can help with shedding, breakage, and regrowth. But unlike rosemary oil and vitamin B5, both of which have studies that back up their aid in hair growth, scientific evidence surrounding castor oil is lacking. (Any testimonials about castor oil for hair growth are anecdotal, coming mostly from blogs, Reddit, and YouTube.)
The earlier you begin treating hair loss, the more effective the treatment will be. Androgenetic alopecia is a condition that gradually worsens over time, so the general rule is that the earlier you seek treatment, the better. “If you’re losing your hair and you have genetic hair loss, using medication such as Propecia or minoxidil is most effective when started early,” says Dr. Robert M. Bernstein, Dr. Wolfeld’s colleague at Bernstein Medical – Center for Hair Restoration. Because not everyone loses hair on the same timeline, you can’t rely on statistics to tell you when you should start treatment. Some men start to notice thinning in their early 20s, while others maintain a thick head of hair well into their 50s. If you suspect that you’re starting to lose your hair and want it to stop, act quickly.
Spironolactone, brand name Aldactone, is in a class of drugs called potassium-sparing diuretics (often called water pills). Spironolactone is typically used to reduce fluid in your body without causing the loss of potassium. It is also used to treat potassium deficiency, high blood pressure (hypertension), swelling (edema), and a hormonal disorder called hyperaldosteronism.
While trauma can come on suddenly and unexpectedly, you may be able to help manage ongoing stress in your life with exercise, like yoga, or mindfulness techniques, like meditation. Some researchers are even exploring these alternative healing modalities in relation to reversing hair loss. The idea is that yoga and meditation may help regulate blood sugar and enhance circulation, promoting regrowth.
The truth is, the amount of propylene glycol in hair loss treatments is not likely to cause any real harm and the FDA has given the chemical approval for many uses. But even though it is safe, we wanted to ensure that our top picks would be as comfortable to use as possible. So when Dr. Khadavi told us that “a third of my patients get irritated from minoxidil products because of propylene glycol,” we decided to cut any treatments with it. In any case, it’s the minoxidil that helps curb hair loss and not the propylene glycol.
While diet alone won’t save your hair, there may be some truth to the old adage that you are what you eat. “You’re not going to have the healthiest hair if you’re living off doughnuts, because being nutrient-deficient weakens strands and makes them more prone to breakage,” says Denise Kernan, owner of DK Hair Techs, Inc., a member of the International Society for Hair Restoration Surgery, and a hair transplant technician who has worked on everyone from senators to sports stars to actors to mafia guys (she won’t name names to protect the privacy of her clients).
Egg is rich in proteins, sulfur, zinc, iron, selenium, phosphorus, and iodine. The high protein content makes eggs one of the best ingredients that promote hair growth. The natural fats present in eggs moisturize and nourish the hair follicles and hair strands. The vitamins A, E, and D reduce hair fall, improve hair texture, and give your hair a lustrous shine (29).
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
