Hair thickeners don't actually make your hair grow more strands; instead, they create the illusion of thicker hair through several mechanisms. They work by targeting individual hair strands and manipulating their appearance, rather than stimulating hair follicle growth.
Mechanisms of Hair Thickening Products
Several methods are employed by hair thickening products to achieve a fuller look:
-
Coating the hair: Many products contain ingredients that coat each hair strand, increasing its diameter and making it feel and appear thicker. This coating effect creates a fuller, denser look. This is similar to how a coat of paint makes an object appear larger. [Source: Reddit r/HaircareScience, Reddit r/malegrooming, Birmingham Dermatology Clinic Blog]
-
Adding volume and body: Some hair thickeners, especially shampoos and conditioners, add moisture and volume to the hair. This "plumping" effect makes the hair appear thicker and more voluminous, filling in spaces between individual strands. [Source: Reddit r/explainlikeimfive]
-
Utilizing proteins and collagen: Certain shampoos and conditioners contain proteins like keratin (a major component of hair itself) and collagen. These ingredients coat the hair, making the individual shafts appear thicker. [Source: Unnamed source provided in prompt]
-
Temporary Styling Effects: Hair thickening sprays work primarily by creating a temporary hold, making the hair appear thicker and fuller by reducing space between strands and adding structure. They don't impact hair growth or the number of strands you have. [Source: Wimpole Clinic Blog]
It's crucial to understand that these products create a temporary cosmetic effect; they don't increase the actual number of hair follicles or stimulate hair growth.
What to Expect from Hair Thickening Products
-
Improved Appearance: You'll likely see an improvement in your hair's volume and thickness. This is most noticeable when using products that coat and add volume to each strand.
-
No Long-Term Growth: Do not expect hair thickening products to solve hair loss or significantly increase the number of hair follicles. [Source: Quora, Xyon Health Blog, Grow Gorgeous Blog, Salt Grooming Blog]
-
Temporary Effects: The effects of hair thickening sprays and some styling products are temporary and wash out.
Ingredients to Look For
While specific ingredients vary between products, those aiming to thicken hair often include proteins, polymers, and volumizing agents. Always check the ingredient list to understand what's in your chosen product.
