How to Make Fine Hair Thicker: The Ultimate Haircare Routine For Thicker Hair

Thin, fine hair can feel like a constant challenge—whether it’s struggling to create volume, dealing with breakage, or feeling like your hair just doesn’t grow. But the good news is that while some factors, like genetics, may be beyond your control, there are plenty of ways to improve the look and health of your hair. From targeted scalp care to advanced treatments like microneedling and serums, achieving thicker, fuller locks is a realistic goal with the right strategies. In this guide, we’ll explore the causes of thinning hair and provide actionable tips to help you transform your hair from root to tip.

What Causes Hair to Thin?

Hair thinning can be caused by a number of factors, and oftentimes those factors are interconnected. Understanding what may be the cause of thinning hair can help you figure out the best way to treat it.

• Age - As we age, our hair follicles naturally shrink over time, producing finer, weaker hair strands.
• Diet - Your diet plays a crucial role in the health of your hair. If you’re not getting enough proteins or essential vitamins, your hair strands may weaken and grow slower.
• Medical conditions - Underlying health issues often manifest in hair thinning or loss. Conditions like alopecia, thyroid disorders, or even stress can disrupt the hair growth cycle.
• Hormonal changes - Hormones are powerful regulators of hair growth. Fluctuations caused by pregnancy, menopause, birth control, or hormonal imbalances like polycystic ovary syndrome (PCOS) can all impact hair health.
• Styling - Overuse of heat tools like flat irons and blow dryers can weaken the hair shaft, making it prone to breakage. Similarly, chemical treatments like coloring, bleaching, and perming can damage the hair’s cuticle layer, leading to thin, brittle strands.
• Genetics - One of the most significant factors in hair loss and thinning is genetics. Hereditary hair loss, also known as androgenic alopecia, is the most common cause of hair thinning in both men and women. While it cannot be completely reversed, there are ways to slow its progression and improve hair density through treatments.

How To Get Thicker, Fuller Hair

Focus on Scalp Health

Healthy hair starts at the root—literally. If you’re scalp is not well maintained, you aren’t giving it the conditions it needs for healthy hair growth. Focusing on scalp health is one of the most effective ways to encourage hair growth and prevent further thinning. Here’s how to cultivate a scalp environment that promotes stronger, healthier hair.

• Keep your scalp clean - When your scalp accumulates buildup from sebum (natural oils), styling products, and dirt, it can clog hair follicles and obstruct growth. Regular cleansing removes these impurities and helps maintain a healthy scalp. Select a shampoo tailored to your hair type, and incorporate a clarifying shampoo into your routine every 4–5 washes to deeply cleanse your scalp and remove stubborn residue.
• Avoid overwashing - Washing your hair too frequently can lead to dryness, irritation, and excessive shedding. While it’s important to keep your scalp clean, over-cleansing can strip away essential oils that nourish your scalp and hair. If you have a dry scalp, you may find washing your hair 2-3 times a week is best while those with oily scalps may prefer washing every other day.

Moisturize Your Hair

Hair needs moisture to maintain its structure and flexibility. When your hair lacks hydration, it becomes rough, weak, and more likely to split or break. Over time, this can contribute to thinning as damaged strands are unable to grow long and healthy. A consistent moisturizing routine not only prevents damage but also enhances the appearance of fullness and shine. 

• Use a hair mask weekly - A weekly hair mask is an excellent way to deliver a concentrated dose of hydration to your hair. These treatments are designed to penetrate the hair shaft, repairing damage and locking in moisture. Choose hair masks with ingredients like shea butter, coconut oil, argan oil, or hyaluronic acid.
• Co-wash for added hydration - Instead of using shampoo, which can strip your hair of natural oils, try co-washing if you have particularly dry hair. On non-shampoo days, refresh your hair with conditioner only to avoid overstripping your hair.

Consider Your Diet

What you eat nourishes your body—and thus, your hair. 

Hair is made up primarily of keratin, a type of protein, and its growth depends on a variety of nutrients that nourish your body. Without the proper fuel, your hair follicles may weaken, leading to thinning, breakage, and slower growth. By ensuring a nutrient-rich diet, you can strengthen your strands from the inside out.

Incorporate proteins, biotin, omega-3 fatty acids, iron, and vitamins like B-12 and D into your meals. While a balanced diet is the best way to get nutrients, supplements can fill in the gaps if you’re struggling to meet your needs.

Try a Scalp Serum

When it comes to growing fuller hair, Foilin Hair Growth Serum is among the best hair products for growth and thickness. Packed with a powerful blend of peptides and growth factors, Folitin nourishes the scalp, stimulates regrowth, and strengthens existing hair, making it an essential tool in your journey to healthier, more voluminous locks.

Here’s what makes it special:

• Scalp health - Folitin’s blend of peptides, including antioxidant and anti-inflammatory agents, helps create an optimal environment for hair to thrive. By soothing the scalp, Folitin keeps your follicles clear and ready for growth.
• Hair regrowth - Unlike traditional serums, Folitin directly targets hair follicles with peptides that encourage dormant follicles to reactivate. This means you’re not just maintaining your existing hair—you’re actively promoting the growth of new, thicker strands.
• Revitalizing hair - Folitin goes beyond regrowth by strengthening the hair you already have. Its unique formulation improves the structure of each strand, resulting in hair that’s shinier, stronger, and more resilient to breakage.

Just apply 2–3 drops of the serum to clean, dry scalp areas regularly, focusing on saturating the roots, and massage your scalp gently to boost circulation.

Try Microneedling

Microneedling, or derma-rolling, is a technique that uses tiny needles to create micro-injuries on the scalp. Microneedling can help:

• Stimulate collagen production - Collagen is a protein that supports skin elasticity and follicle strength. By boosting collagen production, microneedling helps create a healthier scalp for hair to grow.
• Improve blood circulation - The tiny injuries caused by microneedling enhance blood flow to the scalp. This increased circulation delivers more oxygen and nutrients to hair follicles, promoting growth and vitality.
• Enhance product absorption - Microneedling improves the absorption of topical treatments, such as scalp serums or growth-promoting products. The microchannels created by the needles allow active ingredients to penetrate deeper into the scalp, making treatments more effective.

Before you start microneeding, it’s best to consult a professional for personalized advice, especially if you have a scalp condition.

Use Thickening Products 

Thickening products can provide an immediate boost to the appearance of your hair, making it look fuller and more voluminous when styling your hair. While these products don’t change the actual thickness of individual strands or stimulate growth, they are an excellent option for enhancing your hair’s texture and density while you work on long-term solutions. Try incorporating products like dry shampoo, texturizing sprays, thickening mousses, and volumizing powders into your styling routine.

Thicker, healthier hair doesn’t happen overnight, but with the right care and attention, you can make a noticeable difference. From nourishing your scalp to strengthening your strands, each step you take brings you closer to the hair you’ve always wanted. Whether you’re exploring scalp serums like Folitin, incorporating microneedling, or rethinking your diet, consistency and persistence are key. Stick with these strategies, and over time, you’ll see results that not only look great but feel great, too.
