Thickening Shampoo and Conditioner

Thickening shampoos and conditioners are specially formulated hair care products designed to add volume and fullness to fine or thinning hair. These products often contain ingredients such as saw palmettoginseng, and caffeine, which may promote hair growth, increase hair thickness, and improve scalp health in those with certain hair loss conditions, however, more research is needed.

Hair Pomade

Hair pomades can create the illusion of thicker hair by adding volume and texture. When applied to the hair, pomade coats each strand, making the hair appear fuller and denser. Additionally, certain types of hair pomades use key ingredients, such as saw palmetto and caffeine, that may help stimulate healthy hair growth.

Hair Supplements

Hair supplements typically contain a combination of vitamins, minerals, amino acids, and other nutrients that are believed to be essential for strong, healthy hair. Common ingredients found in hair supplements include biotin, saw palmetto, collagen, zinc, and vitamin C.

While some individuals may experience improvements in hair quality and growth with the use of hair supplements, their effectiveness can vary depending on individual factors and the underlying cause of hair loss or shedding.

Proper Diet

Incorporating a balanced diet rich in vitamins and minerals, such as B vitamins, zinc, iron, and vitamin C, is essential for healthy hair growth. Consuming foods like eggs, nuts, leafy greens, fortified breakfast cereals, oats, yogurt, and fruits may contribute to healthier and thicker hair.

Homemade Hair Mask

Making a homemade hair mask is a simple and natural way to nourish and condition your hair and scalp. This DIY hair mask is packed with vitamins and healthy fats, which may help hydrate and strengthen your hair, adding to your scalp and hair’s overall health.

To do so: 


  • Mash a ripe avocado and mix it with a tablespoon of honey and a tablespoon of coconut or olive oil. Blend the ingredients thoroughly until you have a smooth mixture.
  • Apply the mask to damp hair, ensuring you cover your scalp and hair thoroughly. 
  • Leave it on for about 20 minutes to allow the nutrients to penetrate the hair follicles. 
  • Rinse thoroughly with lukewarm water and shampoo as usual. 

 If you haven’t used these ingredients before, consider patch testing to check for allergies or sensitivities.

Rosemary Oil

According to research, applying rosemary oil to the scalp every day for several months may lead to increased hair growth in individuals who have a hair loss condition. Keep in mind that more research is still needed.

Scalp Massage

Regular scalp massages may improve blood circulation to the hair follicles and stimulate growth. Research notes that having a scalp massage for a few minutes every day may lead to increased hair thickness.

Prioritize Scalp Health

Avoid products with fragrance, silicones, artificial colors, phthalates, ethanol, propyl alcohol, and isopropyl alcohol, as these can dry out and damage the hair follicle and scalp. By checking ingredients carefully, you can ensure overall scalp health, which is directly connected to hair growth and thickness, according to research.

Avoid the Use of Hot Tools Every Day

Hot tools, such as blow dryers, flat irons, and curling irons can cause hair breakage and damage hair overtime. If possible, avoid using these tools every day and use a heat protectant spray to prevent further hair damage. In addition, try to use the lowest heat setting possible when styling your hair, as high heat can weaken hair, and lead to split ends and hair breakage.

Manage Stress

High levels of cortisol, the body’s main stress hormone, are associated with hair loss, as well as scalp dryness. However, managing stress, through techniques like meditation or yoga, can help promote hair and scalp health, while preventing or reducing further hair loss caused by long-term stress.

Scientifically Proven Ways to Grow Thicker Hair

Scientifically proven ways to thicken hair typically revolve around addressing underlying causes of hair thinning and promoting a healthy scalp.

It’s best to consult with your healthcare provider prior to trying any new treatment to ensure that it will work best for your needs. If you experience any serious side effects, including swelling, chest pain, or breathing difficulties, seek urgent medical care.


Minoxidil is an FDA-approved topical medication used to treat male and female pattern hair loss. Offered as a foam or solution, when applied directly to the scalp, minoxidil works by widening blood vessels and increasing blood flow to hair follicles, which can lead to improved follicle function and hair growth. It is believed to extend the growth phase of hair, resulting in thicker and longer hair over time. 


Finasteride is an FDA-approved oral medication used to treat male pattern hair loss. It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone associated with hair loss. By reducing DHT levels, finasteride helps slow down hair loss and promotes hair growth and hair thickness in some individuals.
