Hair is usually linked to the feeling of confidence and self-esteem of a person. One of the most common symptoms that people tend to find solutions for is the thinning of hair. Hair filler is one of the innovative hair treatments that have become popular over the last few years. The improvement of hair thickness and the provision of the needed strength are among the advantages that hair filler treatments offer. However, the question still remains, what is hair filler and how does it work? Let us investigate the matter further.

Understanding Hair Filler:

Thin VS Thick Hair

Hair filler is a targeted treatment for the scalp and hair that involves the application of injectable or topical products to the hair to increase thickness, stimulate growth, and repair the damaged hair. It is essentially a comparison with facial dermal fillers in terms of its revitalizing effects, however, the mechanism of action is different; hair follicles and the scalp environment are newly endowed with nutrients instead of skin being filled up.The main element for the majority of professional hair filler items is hyaluronic acid , a substance that is naturally present in the human body and is famous for its strong water retention capability. To accompany hyaluronic acid, these fillers have peptides, amino acids, vitamins, and growth factors which are the nutrients for the scalp and hair follicles. When combined, these ingredients intend to make the scalp a healthy environment for the hair to be strong and thick.

Hair fillers are available in two main types:

  1. Injectable Hair Fillers: Microinjections are the method through which a dermatologist or a qualified professional injects these fillers directly into the scalp.
  2. Topical Hair Fillers: These are external applications that are found in salon treatments or home-use products and work slowly over time.

How Hair Filler Works:

Structure of the Hair Follicle

The procedure for hair filler treatment usually begins with a consultation that includes an assessment of the degree of hair loss or scalp condition. As for injectable treatments, a number of microinjections introduce the filler mixture into the scalp, which is generally the concentration of the area where hair is thin or weak.

Here is the explanation of the ingredients:

  1. Hyaluronic Acid: Makes the scalp absorb water deeply, hence improving the elasticity of the skin and creating a perfect environment for hair to grow.
  2. Peptides and Growth Factors: Make the hair follicles active that are silent and help to start regrowth.
  3. Amino Acids and Vitamins: Are the essential nutrients that both strengthen hair and prevent it from breaking.
This mixture improves the flow of the blood in the scalp, gives the scalp the necessary nutrients through the hair follicles, and thus the hair becomes thicker and stronger. The best results are usually obtained after a course of treatments.Sometimes treatments are carried out a few weeks apart from which involves the density and shine of the hair visibly improving after several sessions.

Benefits of Hair Filler:

Boosting Hair Thickness & Confidence
