Hair thickening refers to methods, products, or treatments aimed at making hair appear fuller, denser, and more voluminous. It focuses on either increasing the diameter of individual hair strands or improving the overall volume of the hair on the scalp.
How Hair Thickening Works
Hair thickening can occur in two ways:
- Cosmetic Thickening:
- Products coat the hair shaft, temporarily increasing the diameter of each strand.
- Creates the appearance of fuller hair but doesn’t change the hair’s actual structure or growth.
- Structural Improvement:
- Treatments or supplements improve the health of hair follicles, leading to stronger, healthier strands.
- Targets issues like hair thinning, hair loss, or weak hair.
Common Causes of Hair Thinning
- Genetics (e.g., androgenic alopecia)
- Aging
- Hormonal changes
- Nutritional deficiencies
- Stress or medical conditions
- Overuse of heat styling, chemicals, or harsh products
Methods for Hair Thickening
- Shampoos and Conditioners:
- Contain polymers, proteins, or ingredients like biotin, keratin, or collagen to coat hair strands and add volume.
- Thickening Treatments:
- Include serums, mousses, or sprays that provide temporary lift and fullness.
- Scalp Treatments:
- Promote healthier follicles with ingredients like caffeine, niacin, or essential oils (e.g., peppermint or rosemary).
- Dietary Supplements:
- Biotin, collagen, iron, zinc, and omega-3 fatty acids support hair growth and thickness.
- Professional Treatments:
- Keratin or protein treatments, PRP (platelet-rich plasma) therapy, or microneedling for improving hair density.
- Lifestyle Adjustments:
- Avoid over-washing, reduce heat styling, and use protective hairstyles to maintain hair health.

What is the difference between collagen, biotin and keratin?
Collagen, biotin, and keratin are all essential components that play roles in maintaining the health of hair, skin, and nails, but they differ in their structure, functions, and how they support hair health. Here’s a breakdown:
1. Collagen
- What It Is: A structural protein found in connective tissues, including skin, tendons, and ligaments.
- Role in Hair:
- Provides amino acids (like proline) that the body uses to produce keratin.
- Improves scalp health by maintaining skin elasticity and hydration.
- May help prevent hair follicle damage by acting as an antioxidant.
- Common Sources: Bone broth, marine collagen, supplements.
- Best For: Strengthening hair roots, maintaining scalp health, and improving hair elasticity.
2. Biotin (Vitamin B7)
- What It Is: A water-soluble B-vitamin essential for energy metabolism.
- Role in Hair:
- Promotes keratin production, which strengthens the hair shaft.
- Improves hair thickness and reduces brittleness.
- Supports hair growth by improving cell metabolism.
- Common Sources: Eggs, nuts, seeds, bananas, supplements.
- Best For: People with biotin deficiency experiencing hair thinning or slow growth.
3. Keratin
- What It Is: A fibrous structural protein that forms the building block of hair, skin, and nails.
- Role in Hair:
- Makes up the majority of the hair’s structure.
- Strengthens and smooths the hair shaft, reducing frizz and breakage.
- Enhances hair’s resilience and shine when applied topically or treated in salons.
- Common Sources: Naturally produced by the body; hydrolyzed keratin can be found in shampoos or treatments.
- Best For: Strengthening damaged hair and improving hair texture and appearance.
Key Differences
| Property | Collagen | Biotin | Keratin |
|---|---|---|---|
| Type | Structural protein | B-vitamin | Fibrous protein |
| Focus | Scalp and skin health | Hair growth and thickness | Hair strength and structure |
| Function | Provides amino acids to produce keratin; supports skin elasticity | Supports cell metabolism and keratin production | Directly forms hair’s structure, improves resilience |
| Use in Products | Supplements, collagen powders, shampoos | Oral supplements, biotin-infused shampoos | Hair treatments, keratin-rich shampoos |
Which One Should You Choose?
- For Weak or Damaged Hair: Keratin (topical or treatment) to repair and strengthen strands.
- For Hair Growth and Thickness: Biotin, especially if dealing with hair loss or brittleness.
- For Overall Scalp and Hair Health: Collagen to support skin health and provide essential building blocks for keratin.
