While building muscle through exercise does not directly cause hair loss, certain muscle-building supplements and steroids may contribute to hair loss. During exercise, the body experiences a temporary increase in testosterone, cortisol, and Reactive Oxygen Species (ROS). These metabolic byproducts can affect hair follicles, but studies have found that exercise does not cause long-term increases in these hormones. Additionally, practices associated with muscle-building, such as the keto diet, consuming whey protein powder, or taking anabolic steroids, may cause or accelerate hair loss. Maintaining a balanced diet and proper scalp care can help mitigate the indirect effects of exercise on hair health.

What You'll Learn

Testosterone and cortisol increase
Testosterone is a hormone that plays a crucial role in muscle building and bone mass development. It is well-known that elevated testosterone levels can aid in muscle growth. However, the relationship between muscle mass and testosterone is complex. While increasing testosterone levels can promote muscle growth, it is unclear if building muscle directly increases testosterone levels.
Research suggests that exercise, particularly strength training and weight-lifting, can lead to a temporary boost in testosterone levels. The duration of this boost can vary, ranging from 15 minutes to an hour after exercise. However, it is important to note that the effects of exercise on testosterone levels may depend on various factors, including age, fitness level, and the time of day. Older men may experience a less pronounced post-exercise boost in testosterone, and individuals who are not in great shape may see a more significant initial increase. Additionally, testosterone levels tend to be higher in the morning and lower in the afternoon, so evening workouts may result in a more substantial boost.
To optimize testosterone levels, it is recommended to maintain a consistent exercise routine and incorporate specific exercises such as leg workouts and compound movements like squats and bench presses. A well-rounded diet that includes healthy fats and a balance of protein, carbohydrates, and overall nutrition is also crucial for supporting hormone balance. Managing stress levels is another important factor, as stress can elevate cortisol, a catabolic hormone that inhibits muscle growth and negatively affects testosterone levels.
While building muscle mass does not directly cause an increase in testosterone levels, creating a favourable hormonal environment by managing cortisol levels and optimizing testosterone can enhance muscle-building potential. This involves incorporating stress management techniques, a balanced diet, and a well-structured exercise regimen that considers training frequency, intensity, and duration. By doing so, individuals can promote a positive hormonal environment conducive to muscle growth.

Supplements and steroids
Creatine
Creatine is a popular supplement used to boost athletic performance and aid muscle recovery. It is a compound produced naturally in the body by the liver, kidneys, and pancreas and can also be found in protein-rich foods such as meat and fish. While creatine has not been directly linked to hair loss, studies have shown that it can raise testosterone levels and increase DHT (dihydrotestosterone) levels, which is a hormone known to cause androgenetic alopecia in men. As such, those with a genetic predisposition to male pattern baldness may want to avoid creatine supplements.
Protein Shakes
Protein shakes that are 100% whey or egg-based and free from additives are unlikely to contribute to hair loss. However, protein shakes with only a certain percentage of protein concentrate may contain other compounds that could potentially lead to adverse side effects. Additionally, an excessive intake of protein can stress the liver and kidneys over time.
Anabolic Steroids
Anabolic steroids are synthetic versions of hormones found naturally in the body, such as testosterone. They are commonly used by athletes, bodybuilders, and individuals seeking to enhance their muscle mass, strength, and physical appearance. While anabolic steroids can be effective in achieving these goals, they can also have serious side effects, including permanent hair loss, particularly in those with a genetic predisposition to male pattern baldness. Anabolic steroids can stimulate the production of DHT, which damages hair follicles and leads to significant hair loss.
Corticosteroids
Corticosteroids are a type of medication used to treat various conditions such as asthma and certain types of cancer. While hair thinning or loss is a less common side effect of corticosteroids compared to anabolic steroids, it can still occur. However, this side effect may be reversible if the medication is stopped under medical supervision.

Workout hairstyles
Working out does not cause hair loss. However, tight hairstyles can lead to hair breakage. Here are some workout hairstyles that are effective in preventing hair breakage:
Braided High Pigtails
Create two high ponytails and braid the lengths of your hair. You can also add some hair oil or leave-in conditioner to your hair before styling.
The Flip Twist
Pull your hair into a low, loose ponytail, then flip the lengths of the ponytail through the centre of the hair above the hair tie. Separate your hair into two low ponytails and repeat the flip-twist process down each side.
The Half-Up High Pony
This hairstyle is ideal for low-intensity workouts and strength training. If you have thinner hair, use a thick scrunchie to beef up your ponytail and give it a '90s look.
French Braids
French braids provide excellent hold and keep your hair close to the scalp, making them perfect for activities like running or cycling.
Dutch Braids
Dutch braids are similar to French braids but with more volume. They are great for women with thicker hair who need added control.
The Classic Ponytail
The classic ponytail is a versatile and easy hairstyle for almost any type of workout. It keeps your hair off your face and neck, allowing you to focus on your workout. However, be mindful of the tension at the hairline to prevent breakage.
The Ballet Bun
Pull your hair into a high ponytail, coil the lengths into a bun, and secure it with bobby pins. This is a great low-tension hairstyle, especially if you struggle with braiding your hair.
The Crew Cut
The crew cut is a versatile and stylish option for men with thinning hair. It is similar to the buzz cut but slightly longer on top, maintaining a neat and polished appearance without drawing attention to areas of hair loss.
The Textured Crop
The textured crop adds volume and dimension to thinning hair. This hairstyle creates the illusion of thicker hair and can be easily styled with a small amount of pomade or styling cream.

Sweat and scalp care
While building muscle through regular exercise does not cause hair loss, excessive sweating can. The scalp has innumerable sweat glands, and the sweat can cause greasy hair and a dried scalp, which can lead to dandruff. Excessive scalp sweating can also lead to weaker hair roots and hair loss. The salts left behind when sweat evaporates can change the texture of hair and damage coloured hair.
To prevent scalp sweating and maintain scalp health, it is important to keep your scalp and hair clean by washing them regularly with a gentle shampoo. This helps to remove excess oil, sweat, and dirt, preventing buildup and promoting a fresh, clean feeling. Washing your hair 2-3 times a week with a gentle shampoo will maintain scalp health without over-drying. There are also shampoos specifically formulated for sweaty scalps that can help revitalise the life of your hair and your scalp. Essential oils like tea tree oil, peppermint oil, and rosemary oil are beneficial for managing a sweaty scalp due to their natural antiseptic and astringent properties.
In addition to maintaining good hair hygiene, limiting the use of heat styling tools such as hair dryers, flat irons, and curling wands can help, as excessive heat can stimulate oil production and exacerbate an oily scalp. When using heat tools, use a heat protection spray first. Reducing your intake of spicy foods and caffeine can also help, as these can stimulate the sweat glands and lead to increased oil production on the scalp.
If you are concerned about hair loss due to sweating, consulting a dermatologist can help you find the right solutions.

Diet and nutrition
While exercise and building muscle do not directly cause hair loss, nutritional deficiencies can. A balanced diet is key to nourishing your hair from the inside out. Hair thrives on a diet rich in protein, vitamins, and minerals. Nutritional deficiencies in vitamins like Biotin (B7), Vitamin D, and minerals such as zinc, iron, and protein can impede hair growth and contribute to hair loss.
Some bodybuilders follow strict diets to support their training regimens, which sometimes lead to nutritional deficiencies. If you are working out, it is important to ensure your diet meets the demands of your training. The keto diet, for example, is so restrictive that it can deprive your body of the vitamins, minerals, protein, and calories it needs to grow hair.
Additionally, supplements and steroids aimed at building muscle can also contribute to hair loss. These substances mimic male hormones, which can increase their masculinizing effects. For instance, whey protein isolate supplements can accelerate hair loss in males who are experiencing some degree of hereditary male pattern hair loss. Similarly, creatine supplements are popular among athletes for their muscle-building benefits, but there is limited research on whether they cause hair loss.
In summary, while building muscle does not directly cause hair loss, nutritional deficiencies, certain supplements, and steroids associated with muscle-building can contribute to hair loss. It is important to maintain a balanced diet and consult a healthcare professional if you are concerned about hair loss.
