In recent years, more and more brands and manufacturers want to add hydrolyzed sponge to anti-hair-loss and hair-growth products. They keep asking us the same question:

“Can hydrolyzed sponge really promote hair growth? Is there any research data to support it?”

As a professional manufacturer of hydrolyzed sponge, we decided to let the data speak. We sent our hydrolyzed sponge samples to a university laboratory and commissioned a research team to conduct a systematic study on “the role of hydrolyzed sponge spicules in promoting hair growth.” The study was finally published in the international academic journal International Journal of Pharmaceutics.

Today, as the raw material manufacturer, we provide a complete interpretation of this experiment — so you can clearly see: what hydrolyzed sponge does in the hair growth field, how it works, and what the results are.

1. What problem does the study aim to solve?
Core problem: Many active ingredients with hair-growth potential (e.g., proteins, peptides, growth factors) have large molecular weights and struggle to penetrate the stratum corneum to reach the depth of hair follicles. How to achieve safe, efficient, painless transdermal delivery is a major challenge.

Research approach: Use the natural spicule structure of hydrolyzed sponge as a transdermal delivery carrier for active ingredients, and investigate whether it can deliver large-molecule active ingredients deep into the skin and ultimately promote hair growth.

2. Experimental design (focusing on the experiment itself)
2.1 Material sources
The study clearly records the sources of key materials. The hydrolyzed sponge spicule extract powder was provided by our company (Hunan Sunshine Bio-Tech Co., Ltd.).

2.2 Cellular experiments
Subject: Human dermal papilla cells — the “engine” of hair follicles, whose activity directly determines whether follicles enter the growth phase.

Method: Apply different concentrations of the active ingredient to dermal papilla cells and measure cell proliferation.

Key data: At 2000 μg/mL, the active ingredient significantly promoted the proliferation and aggregation of dermal papilla cells.

Conclusion: The active ingredient itself has biological activity that activates dermal papilla cells.

2.3 Formulation and transdermal experiments
Subject: Hydrolyzed sponge spicule system (loaded with active ingredient vesicles)

Method: Prepare a serum containing the active ingredient and hydrolyzed sponge spicules; test the skin penetration rate and deposition depth of large-molecule proteins via in vitro transdermal experiments.

Key data: Compared with other formulations, the system containing hydrolyzed sponge spicules achieved the highest skin penetration rate of large-molecule proteins, and the active ingredient was deposited into the deepest skin layers (reaching the dermis and below where hair follicles are located).

Conclusion: Hydrolyzed sponge spicules can effectively carry large-molecule active ingredients through the skin barrier and reach deep layers.

2.4 Human clinical experiment
Subjects: Healthy volunteers (scalp application)

Method: Apply the serum containing hydrolyzed sponge spicules + active ingredient to the scalp, and measure various indicators after 14 and 30 days.

Key data:

Indicator        Day 14        Day 30
Hair length        Significantly elongated        Further elongated
Melanin content        Significantly increased        Continuously increased
Skin hydration        Improved        Significantly improved
Erythema index        Decreased        Continuously decreased
Safety observation: No skin irritation was observed throughout the experiment. The decrease in erythema index indicates the system is mild to the scalp.

Conclusion: The hydrolyzed sponge spicule system significantly promotes hair growth within 14–30 days, and is safe and non-irritating.

3. Logical chain of the three experiments
Experiment level        Question answered        Conclusion
Cellular experiment        Is the active ingredient itself effective?        Yes, it activates dermal papilla cells
Transdermal experiment        Can hydrolyzed sponge deliver the active ingredient?        Yes, to the deepest skin layers
Human experiment        Does scalp application really grow hair?        Yes, visible in 14 days, more obvious in 30 days, no irritation
All three experiments passed, forming a complete chain of evidence.

4. What does this study tell us?
As the raw material manufacturer, we extract two core messages:

4.1 Hydrolyzed sponge spicules solve the “difficult transdermal delivery” problem
Many active ingredients are potent but have low skin penetration. The natural spicule structure of hydrolyzed sponge can safely and painlessly create micro-channels, allowing large-molecule active ingredients to truly reach the depth of hair follicles.

4.2 The hydrolyzed sponge spicule system is validated in humans
This is not just a cell experiment — it includes human clinical validation. The 14‑day and 30‑day data all point to the same conclusion: hair grows longer, melanin increases, and there is no irritation.

As a manufacturer, the question we fear most is “Do you have data?” — but we can confidently answer: Yes, and it is published in a peer‑reviewed journal.

This study proves that hydrolyzed sponge spicules can safely and efficiently deliver active ingredients to the deep hair follicle layer, significantly promoting hair growth within 14–30 days while improving scalp health.

If you are developing anti‑hair‑loss or hair‑growth products, or looking for a natural penetration‑enhancing ingredient to differentiate your formulation — please contact us. Hydrolyzed sponge is your best choice.
