Why the Keto Diet May be Bad for Hair

Fad diets are all the rage. They come out. They’re endorsed by some big names. You might lose a few kilos, and then before you can say ‘wait, where’s my hair gone?’ you’ve put on the weight you’ve lost and then some!

A popular diet doing the rounds at the moment is the Keto diet. It seems too good to be true. Everyone from Kim Kardashian to Halle Berry have sworn by the concept… but before you give up on carbs and say goodbye to sweets, consider what’s best for you and the health of your hair. Elimination diets might help shed some of the kilos quickly, but you don’t want to shed your hair in the process too!

We spoke to one of our head scientists, to find out why Keto may have a negative impact on your mane…

  1. Cut-Down of Fruit
    Since ancient times, quality fruit and vegetables are known to be the key to great health, but these seem to be lacking in the Keto diet. Fruit and veggies are loaded with vitamins and antioxidants that play an imperative role in the health of your hair, increasing shine, strength and vitality.
  2. Limited Carbohydrates
    One of the main reasons the Keto is not great for the health of your hair is because it limits the amount of carbohydrates in your diet to under 10%. This, naturally, would see a decrease in fruit and vegetables. Whilst greens will be abundant, the elimination of low GI carbs like sweet potatoes and root veggies may inhibit hair growth, slowing down overall length and making strands dull and lifeless. Your body, by nature, chooses to distribute nutrients to the vital organs in your body, so as soon as you restrict your diet, parts of your body like your hair, skin and nails are the first to be depleted.
  3. A Long-term No-No
    Any kind of diet that cuts out major food groups is putting you at risk of lacking some important nutrients. While you might not feel an impact instantly, you may notice deficiencies over an extended period of time that could lead to unhealthy outcomes such as weak nails, brittle hair and fatigue.
  4. Reversing the Damage Can be Hard
    Its wise to tread with caution when changing your diet regime. It is probably even a good idea to consult your doctor if you’re thinking about eliminating certain foods completely in order to avoid any nasty side effects. Whilst these side effects may take a while to be noticeable, it will take even longer to reverse the damage when reverting back to a balanced diet.

In essence, you want a diet that isn’t just going to help you lose weight, but boost your health overall, which will also shine through in the look and feel of your hair. For healthy and lustrous locks stick to a nutritious, balanced diet that contains all the food groups and use évolis Professional to nourish from root to tip.
