Best Oils for Thicker Hair: Our Top 5 Picks

If you’re on a journey to achieve fuller, stronger, and thicker hair, choosing the right hair oil is crucial. In a world flooded with products promising miracle results, natural oils still stand out as some of the best hair oils for growth and thickness and for good reason. They nourish the scalp, stimulate dormant hair follicles, and strengthen strands from root to tip.

Whether you're searching for the best hair growth oil, an everyday hairstyle oil, or a lightweight hair serum to enhance volume, this guide highlights the top 5 oils to help you achieve visibly thicker, healthier hair.

1. Rosemary Oil – The Scalp Stimulator for Thicker Strands

When it comes to natural solutions for hair thinning, rosemary oil leads the conversation. Known for its powerful anti-inflammatory and circulatory properties, rosemary oil works deep within the scalp to stimulate blood flow and encourage new hair growth.

Why It’s a Top Pick:

• Increases hair density by reactivating hair follicles
  
  
• Naturally combats DHT-related hair loss
  
  
• Proven in studies to be as effective as minoxidil
  
  

How to Use:

Dilute a few drops of rosemary essential oil with a carrier oil (like coconut or jojoba) and massage into your scalp 2–3 times a week. This regular stimulation not only boosts thickness but also improves scalp health.

Whether used as a stand-alone treatment or mixed into a hair serum, rosemary oil is a go-to for those wanting visible volume and hair regrowth.

 

 

2. Batana Oil – The Secret to Restoring Volume in Damaged Hair

Batana oil is a lesser-known gem that’s rapidly becoming a favourite among those seeking the best hair oils for growth and thickness. Derived from the American palm tree, this thick, golden oil is rich in antioxidants, omega fatty acids, and vitamins A and E.

Batana Oil Benefits:

• Deeply moisturises dry, brittle hair
  
  
• Repairs split ends and restores shine
  
  
• Supports regrowth by nourishing hair follicles
  
  
• Works well for curly, coarse, or chemically treated hair
  
  

Used regularly, batana oil doubles as a hairstyle oil and restorative mask. Apply it as a weekly deep treatment, leaving it on for a few hours before shampooing. It’s especially effective for those experiencing thinning at the crown or temples.

UK users looking for a holistic hair growth oil that also boosts strand thickness will find batana oil to be a powerful, natural solution.

 

 

3. Castor Oil – The Classic for Fuller, Thicker Hair

No list of recommended hair oil for hair growth is complete without castor oil. Thick and nutrient-rich, castor oil has long been used as a remedy for hair fall and thinning edges.

Key Benefits:

• Contains ricinoleic acid that stimulates blood circulation
  
  
• Enhances the growth cycle of hair follicles
  
  
• Strengthens strands and reduces breakage
  
  
• Adds instant volume to thin hair
  
  

Though heavy in texture, castor oil can be diluted with lighter oils or added to your favorite hair serum for a more manageable application. For best results, warm it slightly before applying to your scalp and ends.

It’s especially great for those struggling with bald patches, thinning edges, or postpartum hair loss making it a top contender for the best hair growth oil.

4. Argan Oil – Lightweight Moisture for Finer Hair Types

Looking for something less greasy but equally effective? Argan oil often called “liquid gold”—is perfect for fine hair types that need nourishment without heaviness. Originating from Morocco, argan oil is rich in vitamin E, fatty acids, and antioxidants.

Why Argan Oil Works:

• Protects hair from heat and environmental damage
  
  
• Boosts shine and softness without weighing hair down
  
  
• Reduces frizz and prevents breakage
  
  
• Ideal for use as a hair serum or hairstyle oil
  
  

Apply a small amount to damp or dry hair, focusing on the mid-lengths and ends. It's lightweight enough to be used daily and effective enough to maintain long-term hair health.

Argan oil is ideal for those looking for manageable volume, damage protection, and subtle thickness making it one of the best hair oils for growth and thickness in everyday hair routines.

5. Amla Oil – The Ayurvedic Secret for Hair Volume and Strength

Amla oil, derived from Indian gooseberries, has been used in Ayurvedic medicine for centuries to promote hair growth, strengthen roots, and reduce premature greying. Its high vitamin C content and powerful antioxidants make it a natural volumizer.

Amla Oil Highlights:

• Nourishes the scalp and strengthens follicles
  
  
• Reduces breakage and enhances shine
  
  
• Promotes blood flow to the scalp
  
  
• Ideal for all hair types, especially dull or thinning hair
  
  

To use, massage the oil into the scalp and leave it on overnight. Amla oil can be blended with coconut or sesame oil for enhanced benefits. Over time, it thickens hair strands and revives hair's natural lustre.

In the UK, where harsh weather and water can damage hair, amla oil serves as an affordable and effective hair growth oil for those committed to a natural regimen.

Final Verdict: Which Oil is Best for You?

Choosing the best hair oils for growth and thickness depends largely on your hair type and specific concerns. Here's a quick breakdown to guide you:

• For dry, coarse, or damaged hair: Choose Batana Oil
  
  
• For thinning hair or scalp stimulation: Go with Rosemary Oil
  
  
• For thin hair needing volume: Try Castor Oil
  
  
• For fine or oily hair types: Opt for Argan Oil
  
  
• For a holistic Ayurvedic approach: Pick Amla Oil
  
  

You can also rotate or blend oils depending on your needs for example, use rosemary oil for scalp massages and argan oil as a hair serum for shine and styling.

In fact, clinical research has shown that rosemary oil can be just as effective as minoxidil (a pharmaceutical hair growth treatment) for promoting hair regrowth and increasing density, making it a natural yet science-backed choice for those dealing with thinning hair [source].

Likewise, ancient remedies like amla oil, which have been used in Ayurvedic medicine for centuries, are now supported by modern science for their ability to strengthen roots and improve scalp health [source].

Final Tips for Using Hair Oils:

• Consistency is key: Use oils regularly for long-term results.
  
  
• Scalp massage matters: Massaging increases absorption and boosts circulation.
  
  
• Less is more: Especially with heavier oils like castor and batana apply sparingly.
  
  
• Pair with a healthy lifestyle: Diet, hydration, and stress management also impact hair health.
