What Is Brewer's Yeast?Also known as beer yeast or baker's yeast, brewer's yeast is a by-product of brewing beer and is also used in the production of bread. This type of yeast has many medicinal uses, such as treating respiratory as well as digestive complications. Due to its probiotic properties, it can even be used to aid healthy digestion. It is commonly used as a supplement for nutrition, being rich in chromium as well as B vitamins. Alongside medicinal benefits, brewer's yeast has now become more popular for hair and is even contained in many upper-range anti-ageing skincare. The Benefits Of Using Brewer's Yeast For Hair 1. Hair growth: Brewer's yeast is a dietary supplement made from microscopic fungi. It's an ideal source for healthy hair and nails because it is rich in vitamins B1, B5, B8, B9 and minerals. Hair is primarly made from proteins called keratin and vitamin B is essential for the synthesis of keratin. Keratin acts as a protective agent against external aggressions such as sun, sea water, cold. However, most foods that we consume do not contain enough vitamin B to support all of this. Therefore, yeast is a very good way of filling possible deficiencies. If you are deficient in vitamin B, then it can affect your hair and nails.2. Hairloss: On the flipside, those suffering from hair loss due to weakened hairfollicles or certain genetic factors that want to rescue the current head of hair they have. Not only does brewer's yeast help to fight against hairloss by improving hair growth, but its richness in vitamins and proteins mean that it improves the actual condition of newly grown hair. You can incorporate brewer's yeast into your routine by mixing a DIY hair mask along with olive oil and mineral water. For optimum effect, leave the mask on for one hour before continuing with your usual haircare routine. Weekly use of this formula over a longer period of time will slow down the effects of hair loss and stimulate new hair growth much more rapidly. 3. Application and Results: By regularly consuming yeast, you guarantee that your hair will become stronger and shinier. In case of hair loss, brewer's yeast can also be an effective solution. There are different ways to consume brewer's yeast. The first is in the form of flakes, which can be sprinkled on salads or soups. A few spoons in the form of tablets or capsules once or twice a day will also help you. If you opt for capsules then take them only for about three months; beyond that, the body gets used to it, and dietary supplements are no longer effective. 4. Side effects: Despite the benefits of yeast on the hair, over-consumption can have some side effects. Indeed, it is quite rich in calories (about 300 calories per 100g). However, one or two tablespoons do not exceed 100 calories. Too much can also cause aerophagia if you have a sensitive stomach. To minimise the risk of these side effects, it is recommended to consume brewer's yeast in its inactive form. You should consume brewer's yeast with caution if you're sensitive to gluten, ensuring to choose suitable brands of nutritional yeast. You should avoid brewer's yeast if you're gluten intolerant due to the body's antibodies against some substances contained in it.
