My scalp is sensitive and I often react to fragrances. Should I be cautious with this shampoo?

Yes, a cautious approach is recommended. The product notes clearly state that if your scalp is very sensitive or you react easily to fragranced hair products, you should introduce any new shampoo with attention at first. This is standard, prudent advice for any cosmetic product.

To test it safely, apply a small amount of the diluted shampoo to a discreet area on your inner forearm or behind your ear. Wait 24 hours to check for any redness or irritation before using it on your scalp. When you first use it to wash your hair, focus the lather primarily on your hair lengths and avoid vigorous scrubbing of the scalp. If you experience any itching, redness, or discomfort, stop use immediately. For those with known, significant sensitivities, a fragrance-free, hypoallergenic shampoo might be a more reliable daily option.
