Dry hair usually lacks moisture and may suffer from broken cuticles or weakened strands. Hair packs actively restore lost moisture and help seal the hair cuticle, which natural oils/ conditioners alone may not fully address. With dryness, hair tends to frizz, break, or become brittle — all of which hair packs can help mitigate. Hair packs are best used periodically (e.g. 1–2 times per week, or as needed), not daily — overuse (especially protein-heavy masks) might make hair brittle.
