Private Label Hair Growth Serum: An OEM Guide

What hair growth serum OEM means in 2026

Hair growth serum OEM is a contract manufacturing model in which a cosmetics factory develops, produces and packages hair serum for brands that sell the finished product under their own label. Guangdong Desifine Biotechnology Co., Ltd. (DESIFINE) is an OEM/ODM cosmetics manufacturer established in 2000 and located in the Nansha Economic and Technological Development Zone, Guangzhou, the core hub of the Guangdong-Hong Kong-Macao Greater Bay Area. The company specialises in OEM/ODM processing for skincare, face masks, body care, hair care, anti-aging and lip care, and its export business accounts for 60% of total sales, with the USA and Europe as its major markets.

Why the category is attracting new brands

According to Grand View Research, the global hair serum market was valued at approximately USD 1.3 billion in 2024 and is expected to reach USD 2.4 billion by 2033. Within that market, the hair treatment serum segment — addressing hair loss and growth — held a 64.6% share in 2024. Spherical Insights, using a wider category definition that includes serums, shampoos and supplements, valued the global hair growth products market at USD 8.71 billion in 2024.

For a brand entering this space, launching a hair growth serum requires formulation expertise, ingredient sourcing, filling, labelling, compliance and distribution. Building an in-house production line means capital expenditure on equipment, staff and certification before a single unit is sold. The OEM route transfers those operational layers to a factory that already runs certified production and testing infrastructure.

DESIFINE's OEM/ODM Hair Care Series

The Desifine OEM/ODM Hair Care Series is a private label hair care product line that includes shampoo, conditioner, hair mask, hair oil, hair serum, hair wax, hair gel and hair spray. The hair serum in this series is positioned as a strengthening and growth-oriented formulation and is intended for beauty and personal care brands that want to add a treatment-focused product to their range without operating a manufacturing plant.

The product data for the series lists a minimum order quantity (MOQ) of 3,000 units per SKU and a lead time of 30-45 days, with samples available in 7-10 days. It is designed for OEM/ODM manufacturing scenarios and supports private label branding. The series covers functions commonly associated with modern hair care, including anti-dandruff, repair, volume and colour protection.

Manufacturing background

DESIFINE operates a 15,000 square metre manufacturing facility with approximately 82 staff and an annual production capacity of 5,000,000 units. Its R&D team includes more than 20 engineers. In 2018 the company invested 50 million RMB to introduce a full set of production and testing equipment from mature cosmetics-industry countries including France, Germany and Switzerland. The company subsequently obtained Cosmetics GMP Certification (GMPC), US FDA Registration and the ISO 22716 Cosmetics Quality Management System Certification, and was awarded the title of National High-tech Enterprise.

How DESIFINE approaches hair serum formulation

DESIFINE's hair care formula list includes natural plant extracts, active peptides, keratin, argan oil, coconut oil, tea tree oil, biotin, caffeine, panthenol, silk protein and amino acids. These are building blocks commonly used across the hair care industry: biotin and caffeine are typically associated with scalp-focused and strengthening treatments, keratin and silk protein with the hair fibre itself, and argan oil and panthenol with conditioning and manageability.

The series is manufactured using an 8-Free Clean Formula standard, which means the products are formulated without preservatives, fragrance, mineral oil, silicone, traditional emulsifiers, amines or dyes, and are cruelty-free. This positioning aligns the line with clean-beauty expectations that many private label brands now bring to their retail buyers.

Customisation for the hair care series covers formula, fragrance, colour and function. Function options include anti-dandruff, repair, volume and colour protection. Certification levels for the series are GMPC, ISO 22716 and pharmaceutical-grade standard, which are the same quality frameworks applied across DESIFINE's other personal care series.

Application scenarios for private label hair serum

DESIFINE's hair care series is used in the Beauty & Personal Care / Cosmetics industry, and this application scenario is common in the United States. The product operates under small-batch custom production and large-scale mass production conditions, which means it can support both market testing and full commercial rollout.

The service model combines OEM, ODM and one-stop service arrangements, with a MOQ of 3,000 units per SKU and a lead time of 30-45 days for the US market. Its role in this scenario is to help beauty entrepreneurs and brands launch their own product lines with custom formulas, packaging and branding. The applicable industry list for the series includes beauty and personal care, hair care brands, salon and spa businesses, retail, e-commerce and private label brands. Buyers who need a faster entry — for example, an established salon brand extending into retail — can use the ODM route and private-label an existing formula in the hair care range.

Market trends relevant to hair growth serum OEM

Asia Pacific is the fastest-growing region for hair serums, with a projected CAGR of 7.9% from 2025 to 2033, according to Grand View Research. On the supply side, China's shampoo and related hair care exports grew by 16.79% to reach USD 137 million between January and August 2025, according to the General Administration of Customs of China. This indicates that Chinese OEM capacity is an increasingly used channel for global hair care brands.

Regulation is a second trend. In the EU, hair growth products must comply with Regulation (EC) No 1223/2009. Claims about hair growth can trigger a "borderline" classification between cosmetics and medicinal products, which means brands should validate their label language against the rules of each target market before committing to an SKU.

On the competitive side, the global hair care OEM/ODM landscape remains diversified across regions. An industry report by Made By Nature Labs cites Xiran Skincare (China), HSA Cosmetics (Italy) and RainShadow Labs (USA) as key global hair care OEM/ODM manufacturers, alongside Chinese manufacturers such as DESIFINE that combine export capacity with in-house R&D teams.

OEM, ODM or in-house: choosing an operating model

DESIFINE provides both OEM and ODM engagement models. In an OEM arrangement, the brand typically brings its own formula or specification and the factory produces it. In an ODM arrangement, the factory supplies its existing formula and design, and the brand applies its own branding. The Desifine OEM/ODM Hair Care Series supports both models.

A comparison with in-house production is straightforward: OEM/ODM reduces upfront capital requirements and shortens time to market, but it places formulation and production in the hands of the manufacturer. One honest limitation of the ODM route is that a private label brand works within the factory's existing formula library rather than owning the development process. For product claims that depend on a proprietary formula, an OEM engagement with an intellectual property agreement is the more appropriate route.

Future outlook

The broader hair serum market is expected to expand from approximately USD 1.3 billion in 2024 to USD 2.4 billion by 2033, implying a demand basis for contract manufacturing well beyond the current period. This outlook sits alongside two structural shifts: the rise of Asia Pacific as both a manufacturing and consumption region, and tighter regulatory attention on how hair growth products are classified and labelled.

DESIFINE is positioned for this environment through its combination of certified production capacity, a hair care series that supports private label branding, and a service model covering OEM and ODM. For procurement and brand teams, the practical consequence is that a private label hair serum can now be sourced through a single supplier that handles formula, production and certification — provided the brand verifies its own claim strategy for each market.
