RADICAL strengthening shampoo can be used on its own as a regular cleansing product, or paired with a matching tonic or serum when thinning is more pronounced. In that case, the shampoo should usually come first: cleanse the scalp, rinse thoroughly, gently towel-dry, and then apply any leave-on product according to its own instructions. This order helps avoid leaving sebum, styling residue or pollution particles on the scalp before applying a leave-on formula.
If your scalp is comfortable, you may use this shampoo as your main wash during the 8–12 week routine suggested for anti-hair-loss shampoos. If the scalp feels tight, dry or sensitive after repeated washing, alternate it with a mild moisturising shampoo rather than forcing daily use. This can help keep the scalp comfortable while still giving the strengthening shampoo enough regular contact with the scalp to be meaningful.
For best results, avoid making the routine too aggressive. Massage with fingertips, not nails; do not scrub hard; rinse well; and handle wet hair gently, as wet strands are more vulnerable to mechanical breakage. A wide-tooth comb, less heat styling and looser hairstyles can support the same goal as the shampoo: keeping existing hair from being unnecessarily stressed.
