<\/figure>\n\n\n\nWhat should you confirm before production starts?<\/h2>\n\n\n\n
If you’re preparing to work with a factory on a custom shampoo, first make sure you and the manufacturer agree on what “approved” means. Liking a sample’s fragrance and foam doesn’t mean every production detail has been settled.<\/p>\n\n\n\n
Before scheduling a batch, confirm:<\/p>\n\n\n\n
- \n
- The formula version and its corresponding approved sample.<\/li>\n\n\n\n
- The bottle, cap or pump, label, and intended fill quantity.<\/li>\n\n\n\n
- The product specifications and the process for approving later changes.<\/li>\n<\/ul>\n\n\n\n
For example, approving shampoo in a sample jar doesn’t tell you whether it will dispense properly through your chosen pump. Evaluate the formula and packaging together.<\/strong><\/p>\n\n\n\n
A proposed hair-and-body product needs an intended-use brief that names both applications. The discussion of shampoo use on body skin<\/a> is useful background for separating those performance expectations before the formula and test plan are finalized.<\/p>\n\n\n\n
If you’re still making changes, resolve the relevant custom hair care formulation decisions<\/a> before treating the sample as ready for production.<\/p>\n\n\n\n
For a coordinated care range, the approved sample should also fit the products used alongside it. Our U.S. three-product repair collection example<\/a> describes the formula and packaging decisions connecting a shampoo, conditioner and intensive mask.<\/p>\n\n\n\n
The shampoo manufacturing process: how Keronhair turns a formula into a bottled product<\/h2>\n\n\n\n

<\/figure>\n\n\n\nAt Keronhair, production starts with the confirmed formula, approved sample, and packaging specifications. We work toward the agreed appearance, fragrance, pH, viscosity, and packaging performance for each batch. Our manufacturing process follows six stages, from preparing materials to releasing the finished goods.<\/p>\n\n\n\n
Step 1: Check raw materials, production water, and equipment<\/h3>\n\n\n\n
Before production, we confirm the formula version, batch size, and material list. We check each raw material’s identity, specification, lot number, and status for use, then verify and label the weighed quantities<\/strong> to reduce incorrect, missed, or duplicate additions.<\/p>\n\n\n\n
We also check production water against the required physical, chemical, and microbiological criteria and confirm that tanks, piping, and utensils are clean. The production handover sets out material preparation, temperature control, and sampling requirements. We confirm the formula version before arranging the batch.<\/p>\n\n\n\n
Step 2: Add ingredients in stages and control mixing<\/h3>\n\n\n\n
Following the process instructions, we add water, surfactants, conditioning ingredients, and other materials in stages. Ingredients that need dissolving, dispersing, or hydrating receive the appropriate preparation first. The formula determines whether heating is needed and when fragrance and preservatives are added.<\/p>\n\n\n\n
During mixing, we balance uniformity with air control<\/strong>. Simply increasing the mixer speed can introduce excess air that affects appearance and volumetric filling. When moving from samples to production, we review the tank loading, mixing setup, and temperature conditions for the actual batch size.<\/p>\n\n\n\n
Step 3: Measure and adjust pH and viscosity<\/h3>\n\n\n\n
Once the mixture is uniform, we take samples to check pH and viscosity against the specifications. Before measuring viscosity, we check sample temperature, uniformity, and air bubbles. We record conditions such as spindle and speed so the production batch and approved sample can be compared using the same method<\/strong>.<\/p>\n\n\n\n
Where adjustments are needed, we use agents suited to the formula within the approved limits, record the quantities, and retest. Salt isn’t a universal thickener. The aim is to meet the specifications and suit the packaging; technical and quality staff assess deviations outside the approved process limits.<\/p>\n\n\n\n
Step 4: Check the bulk shampoo before filling<\/h3>\n\n\n\n
Before filling, we sample the bulk shampoo and check appearance, color, odor, and uniformity. We review pH, viscosity, and the microbiological results required at this stage. If bubbles affect appearance or filling, we select an air-control or deaeration method suited to the formula and equipment.<\/p>\n\n\n\n
If we find separation, particles, or results outside specification, we document and investigate the issue. Authorized staff decide how to proceed, and affected properties are checked again after any adjustment. Batch checks don’t replace stability studies:<\/strong> passing one inspection doesn’t establish stability throughout storage.<\/p>\n\n\n\n
Step 5: Fill, close, and check the packaging<\/h3>\n\n\n\n
We confirm the bottles, caps or pumps, label version, and filling specifications before setting up the equipment for the product and container. After checking the initial filled units, we sample fill quantities at defined intervals and inspect closure performance. Pump packs also need checks for priming and smooth dispensing.<\/p>\n\n\n\n
After labeling and coding, we check label placement, batch-code legibility, and finished appearance, then pack the products as agreed. Even when the formula stays the same, changing a cap or pump requires another packaging assessment<\/strong>. Approval of the previous combination doesn’t automatically cover the new one.<\/p>\n\n\n\n
Step 6: Review records, retain samples, and release the batch<\/h3>\n\n\n\n
Completing filling doesn’t mean a batch is released.<\/strong> We review production records, required test results, packaging checks, and the handling of any deviations against the release requirements. An approaching collection date doesn’t justify skipping required tests or leaving issues unresolved.<\/p>\n\n\n\n
The finished batch number connects to raw-material lots and production and packaging records. We retain samples as required for traceability and later investigation. Once quality review and release are complete, we coordinate storage and shipment and provide the batch documentation agreed in the order.<\/p>\n\n\n\n
What ingredients are commonly used in shampoo?<\/h2>\n\n\n\n
Water and cleansing ingredients form the base of a conventional liquid shampoo. Other ingredients adjust feel, flow, preservation, or appearance. Their combined behavior determines the result, so an ingredient list alone can’t tell you how a shampoo will perform<\/strong>.<\/p>\n\n\n\n
