One 2007 laboratory study found that caffeine helped block the effects of DHT in male hair follicles. It stimulated hair shaft elongation, resulting in longer, wider hair roots. It also prolonged anagen duration, which is the hair growth stage.
The testosterone (T) and dihydrotestosterone (DHT) concentrations were measured in the plasma. Our results show that caffeine intake increased the concentrations of T and DHT, organ weight, epithelial cell proliferation and AR tissue expression in the ventral prostatic lobe.
Of the many nutrients and oils touted as natural DHT blockers, rosemary oil is one of the best proven. In a 2015 study, men applied either rosemary oil or minoxidil (an FDA-approved topical treatment for male pattern hair loss) to their scalps twice daily for six months.
Foods rich in lycopene such as tomatoes, watermelons, carrots, and mangoes naturally block DHT production. Biotin-rich foods like berries, liver, legumes, oily fish, and bananas condition the skin and scalp creating an overall healthy environment for strong hair.
A range of medications, products, treatments, and foods may help block the DHT hormone from continuing your hair loss. If your hair is falling out, your dermatologist may tell you that your hair loss is genetic or linked to dihydrotestosterone (DHT).
HairOmega DHT Blocker has Vitamin A, B, 5000mcg Biotin C, E, Zinc, Copper, and Selenium to nourish hair roots and support hair growth for both women & men. Every HairOmega DHT Blocker pill has green tea, Vitamin C, and red raspberry antioxidants reverse free-radical damage and support a healthy immune system.
DHT blockers are safe and effective for most men. However, some DHT-blocking medications may cause side effects, including sexual side effects. The most common side effects of finasteride include decreased libido, erectile dysfunction (ED) and ejaculation issues, such as a reduction in semen volume.
Using zinc as a DHT blocker is not effective. Zinc helps to keep hormone levels regulated, which is one of the reasons why it is so effective in preventing and treating hair loss.
The Relationship Between Caffeine and Your Hair
There's not a lot of scientific research on how caffeine affects human hair growth or hair loss. But the short and sweet news is that — as mentioned above — there's no firm evidence to suggest a link between caffeine and hair loss.
The amount of dihydrotestosterone present in the body from day to day depends on the amount of testosterone present. When levels of testosterone increase, more of it is converted to dihydrotestosterone and so levels of dihydrotestosterone also increase as a result.
The most straightforward way of achieving this is through an oral 5-alpha-reductase (5αr) inhibitor. As the name suggests, these medications inhibit the 5αr enzyme which converts testosterone to DHT. Without a functioning enzyme, DHT levels in the blood plummet which is quickly reflected in the scalp.
Among men, consumption of caffeinated coffee increased total testosterone and decreased total and free estradiol. Among women, decaffeinated coffee decreased total and free testosterone and caffeinated coffee decreased total testosterone.
Caffeine is known to help increase blood circulation to the scalp which promotes healthy hair follicles. When you're massaging hair products directly to the scalp you're aiding blood circulation to the scalp and stimulating the roots.
Some documented side effects of DHT blockers include: erectile dysfunction. ejaculating too early or taking too long to ejaculate. excess fat development and tenderness around the breast area.
However, a small percentage of men who use DHT blockers like finasteride do experience some side effects. These can range from a mild increase in testosterone levels to sexual performance issues such as erectile dysfunction (ED) and a reduced sex drive.
Vitamins Used As DHT Blockers
While multivitamins are good to take for general health, if you want to use vitamins to help block DHT from causing hair loss, biotin supplements are your go-to option.
Biotin doesn't affect the levels of DHT and therefore, it does not address the hair loss seen in male pattern baldness or androgenetic alopecia. It does however been proven to help promote hair growth.
The theory behind using apple cider vinegar for hair loss is that it treats the condition in three ways: Eliminates scalp buildup, removes DHT and balances pH.
DHT is a hormone that contributes to hair loss in both men and women. Green tea, onions, pumpkin seeds, and edamame, among other foods and beverages, contain nutrients that may lower DHT levels and prevent hair loss.
Increased DHT (dihydrotestosterone) can be caused by conditions such as benign prostatic hyperplasia (BPH), prostate cancer, male pattern hair loss (androgenic alopecia), and excessive male-pattern hair growth in females (hirsutism).
Research shows that saw palmetto may be an effective treatment in reducing hair loss due to its anti-inflammatory properties and its ability to block DHT.
