Argan oil is one of the best for fast hair growth and thickness, especially since it undergoes minimal processing. It also protects against heat damage and repairs split ends. It is packed with vitamin E and antioxidants that help improve scalp health and prevent breakage.
It helps to moisturize hair and scalp. Jojoba oil also helps to prevent hair loss and increases hair density and thickness, says Dr Sharad.
Coconut oil all round is simply the best oil for hair thickness and growth. Coconut oil is powerful, so you don't want to leave it in your hair too long. Simply rub it into your hair and scalp and leave it for 30 mins, before giving it a good rinse with your regular shampoo.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
The tl;dr: no. "Castor oil will not grow hair," says Perry Romanowski, a cosmetic chemist and the author of Beginning Cosmetic Chemistry. "There is no evidence for it and no scientific theory supporting that it would work. So yes, it's a total myth."
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
Hair thinning causes can include aging, your genes, shifting hormones, and your diet. Learn what else might be playing a role. Whether you're a woman or a man, it's normal for your hair to thin as you get older, according to Cleveland Clinic.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Whilst thinning hair caused by Male Pattern Baldness will not 'get thicker' again of its own accord, where Telogen Effluvium is the only issue, normal hair growth can resume without intervention so the hair should return to its previous density within approximately six months.
Use minoxidil
Minoxidil (brand name Rogaine) is an over-the-counter liquid or foam applied to the scalp twice a day. It encourages blood flow to the hair follicles to stimulate hair growth (Badri, 2021). Minoxidil seems to work best on younger men (under 40) who've been experiencing hair loss for less than five years.
If you are struggling to regrow hair on the crown of your head, don't forget the power of a healthy diet. Make sure to eat foods rich in protein, magnesium, iron, zinc, and vitamin D. For example, zinc is found in several protein-rich foods, including lean meat, seafood, whole grains, eggs, nuts, and seeds.
Hair on the crown may regrow if the follicles remain intact and unaffected by DHT (a sex hormone that clings to follicles and shrinks them over time). Thinning hairs may also be treated to improve their condition.
"Ironically, with thinning hair it's important to make sure you get your hair cut regularly," says Julie Hensman, from Hensmans in Northampton. "Thinning hair can get out of shape more quickly, making it look more obvious". Booking in for regular trims can keep your hair looking its best.
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
Although hair re-growth may be possible, you should also know when to seek professional help. If the reason for thinning hair is genetics, it will not grow back on its own. To grow back a healthy, full head of hair, you'll need to take action, and that involves reviewing different hair loss options.
Vitamins B and D factor big in healthy hair. So do zinc, omega-3 fatty acids, and the B vitamin biotin. Your doctor can test you for deficiencies. Ask them whether you should take a multivitamin or supplement and how much.
