Beauty Biolage Scalp Care Guide: Rebalancing Oily or Dry Scalps
An educational guide from the Beauty AMZ research team. No hard sell, just what you need to know.
Why scalp care matters
The scalp is skin, and it gets clogged, dry, and irritated like the face does. Buildup blocks follicles and can worsen shedding and odor. A healthy scalp grows healthier-looking hair. Most people neglect it until problems appear.
Reading your scalp type
Oily scalps feel greasy within a day and need clarifying formulas. Dry scalps feel tight and flaky and need gentle hydration. Combination scalps are oily at the crown and dry at the edges. Flaky scalps with itch may need the anti-dandruff formula.
Your weekly routine
Use your targeted shampoo two to three times per week. Add the purifying concentrate once weekly before shampooing. Condition the lengths after every wash. Adjust frequency by season, since scalps get oilier in summer.
Common mistakes to avoid
Do not overwash, since that triggers more oil production. Do not use the concentrate more than weekly. Do not ignore persistent itch or sores, which need a doctor. Avoid heavy oils on the scalp if you are acne-prone there.
When to see a dermatologist
Sores, intense itching, or patchy hair loss need professional care. Scalp psoriasis and eczema need prescription treatment. Do not self-treat these for months. A quick visit gives you the right diagnosis.

Medicated Shampoo on Curly and Coily Hair
Curly and coily hair complicates dandruff treatment because medicated shampoos are drying and textured hair is already moisture-hungry. The routine that works applies the medicated formula to the scalp only, in sections, using an applicator bottle to part the hair and deliver product directly to the skin. Massage with fingertips, leave for the full contact time, then rinse and follow immediately with a deep conditioner on the lengths.
Wash day frequency needs honesty too. The standard advice of medicated washing twice weekly conflicts with curly routines that wash weekly, so compromise with a scalp-only refresh mid-week: dilute the medicated shampoo, apply to the scalp in sections, rinse, and re-moisturize. Pre-pooing the lengths with oil or conditioner before the medicated wash protects the hair from the drying active. Our anti-dandruff guide covers wash-day integration for more hair types.
Dandruff Actives During Pregnancy: What to Know
Pregnancy raises the dandruff question because hormones shift scalp oil production and many people want to check every product. The honest answer is that safety data varies by active and no guide should replace your OB-GYN's advice. Pyrithione zinc has the longest track record in over-the-counter use, while ketoconazole and selenium sulfide have less pregnancy-specific data, which is why many providers suggest minimizing use or switching actives during pregnancy.
Practical steps: bring the ingredient list to your next appointment and ask specifically, rather than stopping treatment and suffering through months of flaking. Salicylic acid in rinse-off shampoo at low concentration is generally considered lower concern than leave-on products, but again, your provider decides. Non-medicated options like gentle zinc formulas or diluted tea tree shampoo can bridge the gap if your provider wants you off medicated actives. Always check with your provider first; our seborrheic dermatitis guide explains when symptoms need more than OTC care.
