Best Scalp Serums For Thinning Hair 

1. Best Scalp Serum for Traction Alopecia (damage from braids and tight hairstyles)

Coco and Eve Tripeptide Hair Density Serum

Traction Alopecia is a type of hair loss that occurs when constant tension is applied to the hair follicles, leading to inflammation, hair loss, and finally follicle damage. This tension can occur as a result of excessively tight hairstyles (think braids or ponytails), super-heavy hair extensions, or even the use of overly tight hair ties.

Some common signs of traction alopecia include:

• Thinning around your hairline or bald spot
• Bald patches in areas under the most tension
• Fractured strands at the site of stress
• Redness or swollen bumps around hair follicles

The Coco and Eve Tripeptide Hair Density Serum uses the power of Redensyl and Procapil to promote the appearance of thicker, fuller hair. Clinically proven to improve hair density by 51% in just one month, this lightweight serum is an ideal choice for those looking to regrow their thinning hair. 

The serum contains ingredients, such as glycoproteins and saw palmetto, which help to calm and soothe the scalp, while slowing down hair loss by blocking DHT conversion and reducing inflammation. This promotes a healthy environment for a balanced hair growth cycle. It also contains Tripeptides and biotin which work together to stimulate collagen production and strengthen hair follicles, as well as Keratin which repairs and protects the hair shaft, reducing breakage and frizz caused by constant tension and pulling.

Amazon user review from Blue Eyed Jeepher:

• I’ve noticed improvements! I’ve been using Coco & Eve’s Tripeptide Hair Density Serum for a few weeks now, and I’m already seeing a noticeable difference in my hair. The serum feels super light and absorbs quickly, which I love. It’s made a huge difference in the thickness and fullness of my hair, and I can definitely see a reduction in shedding! The formula also has caffeine, which I didn’t expect to make a difference, but it really energizes my scalp. My hair feels healthier, and it looks fuller, especially at the roots. Plus, it’s so gentle on my sensitive scalp, and I’ve noticed less irritation. I’ve only been using it for a month, but I can already see why people rave about it. My hair is visibly thicker, and I feel more confident. Highly recommend this serum to anyone dealing with thinning hair or hair loss—it works wonders!

Benefits Of Scalp Serums For Thinning Hair 

1. Nourishes the scalp: One of the essentials of hair growth is a healthy scalp. Ingredients like peptides, oils, and vitamins hydrate the scalp, soothe irritation, and create a good environment for growth. Ingredients like caffeine and menthol also help to increase blood flow to the scalp. This encourages great hair follicle activity, ensuring they receive much-needed nutrients and oxygen.

2. Strengthens hair follicles: Proteins, amino acids, and peptides in scalp serums do a great job of giving essential nutrients that help strengthen and revive your thinning hair from the roots up. Hydrating agents like hyaluronic acid also work to reduce dryness, flakiness, and itching, which helps hydrate and nourish your hair.

3. Reduces inflammation: Inflammation in the scalp can damage hair follicles, leading to hair loss. It essentially alters the hair growth cycle, leading to an increase in the number of hairs in the resting phase. Anti-hair loss ingredients like rosemary oil, aloe vera, tea tree oil, or pumpkin seed extract reduce inflammation by soothing the scalp and supporting blood flow for tension release. 

5. Protects hair from damage: Scalp serums protect your hair from environmental stressors such as UV rays and pollution, which contribute to damage and thinning hair strands.

6. Reduces hair breakage: Regular use of scalp serum strengthens your hair strands, reducing breakage and thinning over time. When our hair becomes a tangled mess, we tend to lose a lot of hair strands because of the wear and tear that goes into detangling. Hair serum acts as a lubricant for such hair and makes detangling easy. 

7. Promotes hair growth and Slows down thinning: Serum ingredients like biotin, caffeine, or minoxidil are known to promote thicker and stronger hair. While ingredients like saw palmetto reduce DHT accumulation, which slows down hair loss caused by pattern baldness.

Key Ingredients To Look Out For In A Scalp Serum For Thinning Hair

• Minoxidil: An ingredient that has been clinically proven to be effective in stimulating hair growth. It works by widening blood vessels in the scalp, increasing blood flow, and allowing for faster delivery of nutrients to hair follicles.

• Caffeine: Stimulates hair growth by improving blood circulation and blocking DHT, a hormone that causes hair loss. 

• Peptides: This protein strengthens hair follicles, signaling them to produce new hair. It also strengthens existing hair and promotes density.

• Niacinamide: Improves blood flow to the scalp, strengthens hair follicles, improves scalp health, and reduces inflammation.

• Rosemary oil: This oil has been proven to stimulate blood circulation to the scalp and promote hair growth. It also possesses antioxidant properties that protect hair follicles from damage.

• Biotin: Biotin is a B vitamin that is essential for healthy hair. It has been shown to promote hair growth by supporting keratin production, enhancing hair thickness, and reducing hair thinning in individuals with biotin deficiencies.

• Saw palmetto: Saw palmetto is a plant extract that is commonly used to treat male pattern baldness. It reduces dihydrotestosterone (DHT) levels, a hormone that is associated with hair loss levels and promotes hair growth. 

• Vitamin B complex: Vitamins B3, B5, and B6 are essential for hair growth; they support the production of keratin (the protein that makes up your hair).

These key ingredients are important when choosing scalp serums for thinning hair. They also work to promote the health of your scalp and existing individual strands. 

Additional Tips

Even with the use of these serums, a conscious effort will do a great job in ensuring you reach and maintain your desired hair goals.

• Ensure you eat a balanced diet; it helps in hair growth
• Reduce excessive heat styling, as it can damage your hair
• Protect your hair from the sun or use UV protection products
• Get regular trims, as they help remove split ends
• Be sure to do a patch test to check for allergies when choosing a new scalp serum
