In order to make hair thicker, assess all factors affecting your hair and then establish a proper hair care regimen. There are natural ways to start growing thicker hair. Hair loss and poor hair health can be directly related to poor diet, hair product chemicals and the elements. Some other things you can do to make hair thicker include getting the proper nutrition in your diet or through supplements and using all-natural hair-care products that can thicken your hair. A diet lacking key nutrients leads to dull, damaged hair. To get healthier, thicker hair, consume appropriate amounts of vitamins A, E and C, as well as biotin and beta-carotene. These are essential for healthy skin and hair. A diet rich in eggs, fish, whole grains, fruits and vegetables will ensure a healthy scalp and thicker hair.

Consider taking a multivitamin to make hair thicker. Avoid inhibitors such alcohol, smoking and junk food. Excessive weight loss and medications can also attribute to hair loss and poor health. A personal regimen that is balanced with good nutrition and regular exercise, such as aerobics and yoga, will ensure healthier, thicker hair from the inside out.
The proper hair care regimen also can help make hair thicker. Aside from choosing a natural shampoo and conditioning regimen, there are additional at-home remedies that produce healthier hair. You also can use various herbal hair remedies that can help make hair thicker.

Oil treatments once or twice a week are a great way to promote hair growth and make hair thicker. Coconut oil, almond oil and olive oil help to maintain a healthy scalp while rebuilding damaged hair. Massage your scalp and hair with coconut oil, almond oil or olive oil. Coconut oil is known to contain antimicrobial agents that fight pathogens which cause scalp irritability. The medium-chain triglycerides (MCTs) found in coconut oil also reduce the loss of hair protein, which can be a result of excessive shampooing and the use of styling products.

Weekly, natural at-home deep moisturizing methods will also help make hair thicker. To strengthen hair and infuse it with protein, try beating two to four eggs — adding enough olive oil to cover the eggs if desired — and apply it throughout dry hair. Uplift treated hair in a shower cap and leave the egg mixture in for 15 minutes before rinsing with cool water. Then shampoo as usual.

To moisturize dull, damaged hair, saturate regular mayonnaise throughout dry hair. Be careful to avoid the roots and scalp if the hair is already oily. Wash your hands, then wrap the treated hair in a shower cap and let it set for an hour. Rinse in cool water, and shampoo as usual.

Factors such as chemicals, the elements, hair tools and hair accessories also affect the hair and scalp. Many shampoos, conditioners and styling products contain harsh chemicals such as sodium laureth sulfate that tend to weaken the scalp and affect hair growth. Choose hair-care products that contain natural ingredients and essential oils to promote healthier, thicker hair.
Frequent washing can strip hair of its natural oils. Washing hair every other day is adequate. A light, leave-in conditioner can be used if tangling is a problem. Avoid breakage by limiting the use of dryers, hot irons and harsh coloring chemicals. Rinse hair in cool or lukewarm water, because hot water causes breakage, and cool water seals hair cuticles.

Abstain from wrapping wet hair in a towel. Finger through wet hair instead, and let it air dry, then comb it using a wooden wide-tooth comb. Let long hair hang loose as much as a possible to avoid further breakage from accessories such as ponytail holders and clamps.
Choose loose hair bands and pins to wear hair up. Trim split ends regularly every four to six weeks. Protect your hair from the elements by wearing a scarf or hat when you are in the penetrating sunlight or a harsh wind.
