Best for Dry Scalp
TRESemme Renewal Hair & Scalp Deep Conditioning Mask
If you have a dry scalp and even drier ends, try this double-duty mask. Part your hair down the middle and rub a dollop of the hydrating cream directly onto your scalp, then comb through. Tea tree oil and sunflower seed oil provide deep conditioning from top (where damage starts) to bottom (where damage shows).
