Biotin Versus Collagen for Hair Thinning
|Primary role||Strengthens hair, reduces hair breakage||Strengthens the hair follicles and increases hair thickness|
|Source type||Vitamin B7||Protein|
|Suitability||Hair thinning from biotin deficiency||Hair thinning from various hair concerns|
|Side effects||Sleeplessness, excessive urination||Allergic response|
Both biotin and collagen are famous supplements for people who are trying to make their hair grow thicker and better.
However, biotin supplements work best only when the reason for hair thinning is biotin deficiency. They might not work as well for other reasons that cause hair thinning.
This is where collagen supplements come into play as they support hair growth and combat hair thinning that happens as a result of a variety of reasons.
Many experts support the use of biotin supplementation to reduce hair loss in people suffering from biotin deficiency because one of the main signs of biotin deficiency is hair loss. (1)
In a study, females diagnosed with biotin deficiency experienced a decrease in hair loss after taking 1,000 micrograms of biotin every day for 3 months. (2)
But if you’re certain biotin deficiency is not your reason for hair thinning, then you may want to go for collagen supplementation.
A study showed that daily use of a nutraceutical containing collagen led to significant improvements in hair growth, volume, and thickness. This supplementation also increased the hair growth rate in the participants. (3)
This is why researchers have deemed collagen supplementation both safe and efficacious in improving hair condition in women experiencing self-perceived thinning hair. (3)
Another study also gave a verdict in favor of collagen as it found that collagen peptides (CPs) can intensify hair regrowth and the growth of human dermal papilla cells. (4)

Role in hair thinning
Biotin is a water-soluble B vitamin and is a widely used ingredient in hair care products such as shampoos and conditioners. It is a famous supplement that people often use to manage their hair troubles. It is known as vitamin B7 or vitamin H.
The research on the exact effect and mechanism of action of biotin for promoting hair health is quite limited. Many experts support the use of biotin for brittle hair, uncombable hair, or hair loss from biotin deficiency. (2)(5) However, for other hair pathologies, biotin is not the supplement of choice. (6)
The supplementation of biotin is mainly recommended for biotin deficiency, and the US FDA advises against using biotin as an everyday supplement with the exception of pregnant women and breastfeeding mothers. (5)
However, in some uncommon cases, biotin toxicity can occur, and its signs can include: (5)
- Increased urination
- Excess thirstiness
Also, if you have diabetes, you should only take biotin after talking to a professional because excess biotin interferes with the body’s glucose control. (5)
The recommended dose for those who suffer from biotin deficiency is 5-35 micrograms. The exact dose that is right for you will depend on your health status and can only be advised by a healthcare professional. (5)

Role in hair thinning
Collagen is the most widely found protein in the body and is very important for maintaining the structural integrity of the muscles, skin, and bones. (7)(8) This is because collagen fibers make body tissues strong and protect them from damage.
Collagen is thought to help with hair thinning as it is good for improving hair density and thickness. Many older people are advised to take collagen supplements because with age, the levels of collagen decrease in the body, resulting in age-related hair loss. (11)
Since collagen is naturally found in the body, not many side effects can be associated with collagen supplementation. However, in some rare cases, collagen obtained from fish extracts may cause allergic reactions. (13)(14)

Can I find vegan collagen?

What are some good food sources of biotin?

In the fight against hair thinning, the choice between biotin and collagen supplements may appear to be very hard.
Biotin, also known as vitamin B7, is essential for people with biotin deficiency-related hair thinning, while collagen supplements are beneficial for various hair concerns.
When choosing between biotin and collagen for hair thinning, consider the root cause of your hair concerns.
