Scalp care basics

The scalp is skin with a high density of hair follicles and oil glands. It can feel dry, tight, oily or uncomfortable, and many people look for products that keep it feeling fresh and balanced. Scalp serums, tonics and leave-on lotions are the main formats for concentrated actives, while shampoos deliver smaller amounts during washing.

The mildly acidic pH

The range of 4.3 to 5.5 matches the naturally slightly acidic scalp surface. Keep scalp products in this range for comfort and to support the stability of the active.

Directions for users

Suggest applying a few drops directly to the scalp after washing, parting the hair in sections and massaging gently. Daily use suits most leave-on scalp serums.

Applicators

Dropper bottles and nozzle applicators make it easy to reach the scalp through the hair.

Sensory check

Ask testers whether hair feels greasy or heavy after the serum dries.

Record keeping

Note the concentrate lot and the final pH of each batch.

Lot records

Keep each CoA with the batch file and note the lot used.

Shampoo version

In a mild shampoo, add the concentrate after the surfactants and before adjusting viscosity with salt. Choose gentle surfactants such as coco glucoside and betaine to keep the scalp comfortable. A matching scalp serum then delivers a leave-on dose between washes.

Questions for the supplier

Ask for the composition, the intended scalp benefit, the recommended level in leave-on and rinse-off products and any test data.

Oily scalp routine

A mild shampoo followed by a leave-on serum gives the scalp care a daily rhythm. Suggest using the serum after each wash.

Storage

Store closed as the CoA directs. Close the container after use.
