Overview
As we age, hair often becomes thinner and weaker, but collagen can help support hair health by promoting keratin production. Collagen strengthens the scalp, reduces hair thinning, and preserves hair color. It's particularly beneficial for those experiencing early hair thinning, but not a cure for severe hair loss or baldness.
Natural collagen sources include bone broth, chicken skin, and fish skin, while marine collagen supplements are especially effective for hair regrowth. Consistency is key for visible results, typically within 3-6 months.
Combining collagen with a balanced diet and healthy lifestyle promotes stronger, fuller hair.
Collagen for Hair Growth: Does It Really Work in 2025?
Did you know that advancing age doesn’t just affect our skin, but also impacts our hair? As we grow older, our hair starts becoming thinner and weaker. If you are experiencing hair problems and wondering, Does Collagen Help with Hair Growth?? You are in the right place.
In this guide, we will answer common questions regarding collagen benefits for hair and share some evidence based results with you. We will also share which collagen supplements you should use for hair and why.
So, let’s get started.
Does Collagen Help with Hair Growth?
For centuries, luscious and thick hair has been considered a sign of beauty and elegance. Even in today’s modern society, hair problems have a strong aesthetic in self-care routines and psychological impact.
Collagen plays an important role in hair health by providing essential amino acids for the production of keratin. Keratin is the main structural protein of hair. Collagen comprises ~70% of the dermis, supporting hair follicles and makes them look thick and beautiful. So, we can say collagen and hair growth are side by side.
According to a study conducted in 2025, consumption of collagen safeguards hair follicle cells and reduces hair loss by improving hair quality and promoting hair growth.
It increases scalp circulation and maintains elasticity while reducing age-related hair thinning. Moreover, its antioxidant properties help preserve natural hair color while preventing premature greying.
Who Should Consider Collagen for Hair Growth?
Collagen is becoming one of the most talked-about supplements for hair health, but it’s important to understand who really benefits the most, and where its limits lie. Collagen supports the scalp, strengthens follicles, and improves hair texture, but it is not a miracle pill for everyone. Below, we break it down into three key groups.
1. People Who May Benefit the Most
Individuals experiencing early hair thinning, breakage, or age-related hair weakness are more likely to notice improvements with consistent collagen use. Collagen provides amino acids that help the body build keratin, which is the structural protein of hair. For women after pregnancy, men facing mild thinning, or older adults dealing with loss of hair strength, collagen can help maintain scalp elasticity, improve shine, and slow down the appearance of thinning.
2. People Who May See Limited Results
It’s important to be realistic. Collagen cannot reverse severe baldness or genetic hair loss on its own. If someone has advanced male or female pattern baldness, they may not see dramatic regrowth from collagen alone. In these cases, clinically proven treatments like minoxidil, PRP therapy, or microneedling are far more effective. Collagen, however, can still be valuable as a supporting nutrient to improve scalp condition and the health of the remaining hair.
3. Using Collagen as Part of a Holistic Hair Care Plan
For best results, collagen should not be taken in isolation. Combining it with a nutrient-rich diet, stress management, and healthy scalp care creates a more complete strategy for stronger hair. Hydration, proper sleep, and avoiding excessive chemical treatments can further enhance collagen’s benefits. In this way, collagen becomes part of a bigger, long-term hair wellness routine rather than a quick fix.
Bottom line: Collagen helps improve thickness, shine, and resilience, but setting the right expectations is key. With consistent use over 3–6 months, most people can track noticeable before and after differences in hair quality, especially when paired with good lifestyle habits.
Sources of Collagen
Though collagen is a naturally produced protein, after the age of twenty our body reduces the production of collagen that leads to aging. Therefore, we need to take collagen from external sources. It is important to understand that for hair nourishment we require type I,II and III collagen.
Natural Collagen Sources
Nature has provided us with various sources of collagen to grow hair. For example,
Category | Food Source | Key Nutrients/Collagen Types | Benefits for Hair |
| Contains Collagen | Bone Broth | Collagen (Type I & III), gelatin, glycine | Strengthens scalp structure; supports hair follicles |
| Chicken Skin | Type II Collagen | Aids scalp and follicle support | |
| Fish Skin & Scales | Marine Collagen (Type I) | Enhances scalp elasticity; supports hair density | |
| Beef (with connective tissue) | Type I & III Collagen | Promotes healthy dermis that anchors hair roots | |
| Pork Skin | Type I Collagen | Improves scalp firmness and follicle strength |
These natural sources are a great way to meet the collagen needs of our body.
However, sometimes, we can’t fulfil collagen requirements due to busy schedules or other reasons. In this scenario, collagen supplements are available to help us to fulfil our requirements.
Collagen Supplements
By incorporating collagen supplements into our daily routine, we can get the same benefits of collagen with no hassle.
Collagen supplements are available in different forms including tablets, powders, gummies and drinks. You can choose from the options that suit you the best.
Moreover, the collagen present in the supplements is taken from different sources such as fish, cows, pigs, chicken etc.
The collagen taken from fish source is known as marine collagen which is the best option for hair growth. A study was conducted in 2022 where they studied the benefits of marine collagen for enhancing hair growth and hair quality. They found fish sourced collagen a great alternative for hair loss prevention and regrowth during alopecia.
How Much Collagen Do You Need Everyday?
Though there are no official guidelines, generally, it is advised to take 2.5-10g daily for 8-12 weeks.
Consistency is key because collagen intake requires patience to see visible results. You may see significant collagen before and after hair improvements in 3-6 months.
Collagen supplements are generally safe. However, choose a manufacturer that provides high quality, Non GMO and cruelty free collagen that contain no fillers and additives.
Vituathority provides high quality Multi Collagen Protein that contains marine,chicken, and bovine sourced collagen with no fillers and additives.
Potential Side Effects
You may experience these side effects with collagen supplements such as digestive issues, skin changes (rare) allergic reactions, slight blood pressure increase. Therefore, it is advised to ask your healthcare practitioner before you start using collagen supplements.

So, does collagen help with hair growth? Absolutely. Research shows that collagen supports keratin production, improves scalp health, and helps reduce hair thinning over time. To see real results, consistency is key.
