One common concern at our hair and scalp spa in Boston is hair loss, which is increasing among all genders and ages. While hormonal imbalances, lifestyle, and genetics play considerable parts in hair loss, research shows that the nutrients we consume, especially sugar, can impact hair health. So, what is the connection between hair loss and sugar?
The Hair Growth Cycle?
Before we discover the link between hair loss and sugar, you need to understand your hair growth cycle. Your head has around 100 thousand hair follicles beneath the scalp skin.
These follicles experience different cycles known as the growth phase, rest phase, and shedding. The active growing stage is the Anagen stage and can last for years. The resting phase, known as the Telogen stage, can last a couple of months before it goes into the shedding (Catagen) phase.
After you shed hair, your new strands return to the growth stage. So, if you want healthy hair, you need a balanced growth cycle, but different aspects, including your diet, can stop the process.
To effectively support healthy hair growth, it’s essential to comprehend the hair growth cycle and how various factors can influence it. One question often arises is how sugar consumption may be related to hair loss.
Can High Amounts of Sugar Cause Hair Loss?
Indeed, a diet high in sugar can lead to hair loss, particularly for individuals with a genetic tendency toward pattern baldness and thinning hair.
There are several mechanisms connected to high levels of sugar consumption, as follows:
Sugar Impacts Hormones in The Endocrine System
Hormones are crucial for the proper functioning of your body. When your hormonal levels are balanced, you can experience optimal health.
However, the intake of refined sugars in sugary drinks and processed foods can lead to fluctuations in blood sugar levels. These spikes in blood sugar are typically met with a rapid insulin response to stabilize glucose levels.
Such erratic swings in blood sugar can interfere with hormone balance, affecting both insulin and androgen hormones.
Insulin Resistance
When blood sugar levels remain stable, this can lead to insulin resistance, which causes the body’s cells to respond less effectively to insulin.
One significant androgen is DHT (dihydrotestosterone), a potent derivative of testosterone. DHT can shrink hair follicles, resulting in a condition known as androgenic alopecia or pattern hair loss.
If you are genetically inclined to experience hair loss and also consume high amounts of sugar, you may worsen your situation.
Sugar Triggers Inflammation and Oxidative Stress
Here is another reason hair loss and sugar are linked: Consuming too much sugar can activate inflammation in the body and contribute to chronic inflammatory conditions.
Hence, the inflammation on your scalp can prevent normal hair growth and lead to hair thinning and loss.
Furthermore, the production of free radicals from sugar metabolism can lead to oxidative stress, which damages hair follicles and impedes the growth of healthy strands.
Leads to Nutrient Deficiencies
While this is not all, it can crowd out the nutrient-dense foods in your diet. These are:
- Biotin
- Iron
- Zinc
- Vitamins A, C, and E
All these nutrients play an essential role in the growth of healthy hair. So, a high-sugar diet with low nutrients deprives your hair follicles of the nourishment they need, leading to weakened strands and hair loss.
Can Hair Loss Be Reversed?
The fantastic news is that you can reverse hair loss caused by high sugar, but you must change your lifestyle and diet. Still, it is not just cutting down your sugar intake; you must make practical changes to improve your scalp health.
- First, limit sugar consumption and refrain from sugary foods, processed snacks, and beverages. Instead, you can eat nutrient-rich food.
- Always read food labels and look for hidden sugars in packaged foods. If you see sucrose, high-fructose corn syrup, or dextrose, these are all added sugars.
- Eat whole grains, vegetables, and fruits that release sugar slowly, and it also prevents rapid blood sugar spikes.
- If you crave sugar, enjoy some maple syrup, stevia, and honey in moderation.
You support a healthy scalp for hair growth when you consume a balanced diet rich in minerals, proteins, and nutrients. We recommend starting your meal with vegetables to help regulate your sugar intake.
Vegetables are high in fiber and low in the glycemic index, and slow down your digestion of sugars. Furthermore, the water and nutrients found in veg increase satiety and reduce the consumption of calories and sugars.
What Vitamins And Minerals Help With Hair Growth
Several vitamins help promote healthy hair growth, but here are the essential ones available in the table below:
| Nutrient | Function for Hair Health |
| Vitamin C | Antioxidant: supports collagen production for hair structure; helps absorb iron necessary for hair growth. |
| Vitamin E | It promotes blood circulation in the scalp, improves follicle health, and protects hair cells from oxidative damage. |
| B-Vitamins | Biotin helps produce keratin, essential for hair structure; B6 and B12 support overall scalp and follicle health. |
| Vitamin D | It plays a role in hair follicle cycling and helps stimulate follicles for new hair growth. |
| Vitamin K | Aids in calcium transport, supporting hair growth and follicle function. |
| Iron | Delivers oxygen to follicles; promotes healthy cell growth; deficiency can cause hair thinning and loss. |
| Zinc | Maintains follicle health, supports cell division, prevents hair loss, and strengthens strands. |
| Selenium | Antioxidant: protects follicles from oxidative damage; supports scalp health. |
| Magnesium | It helps absorb and use other essential nutrients to help maintain strong hair and a healthy scalp. |
| Copper | Supports melanin production (hair color); contributes to follicle health. |
| Silica | Maintains hair strength and thickness; supports collagen formation and strand health. |
| Calcium | Promotes follicle health and nutrient transport to the scalp, supporting hair growth. |
| Potassium | It regulates blood circulation and fluid balance and helps maintain a healthy scalp environment. |
| Iodine | It is essential for thyroid function, which regulates hair growth and prevents hair loss. |
| Manganese | Aids in enzyme production that supports hair growth and overall hair health. |

FAQ
How does a high sugar intake contribute to hair loss?
Consuming high amounts of sugar leads to insulin resistance, increases androgen levels, and helps bind hair follicles. Once the follicles weaken, hair thinning and loss result.
Can reducing your sugar intake help improve hair health?
Yes, reducing your sugar intake can help prevent hair thinning and loss. We recommend a balanced, rich diet in healthy fats, minerals, vitamins, and proteins, and a scalp treatment for hair loss.
Is the natural sugar from fruits harmful to hair health?
The natural sugars in fruit are less harmful to your hair than processed sugars in sodas and candy. It can promote healthy hair growth when taken in moderation with a balanced diet.
How does sugar-induced inflammation affect your hair follicles?
Consuming too much sugar triggers inflammation in the body and the scalp, damaging the hair and disrupting the normal growth cycle. This can lead to hair shedding, thinning, and loss.
