Paul Mitchell Tea Tree Scalp Care Shampoo

Here’s a recommended usage guide:

1. Wet your hair thoroughly.
2. Apply a small amount of the shampoo to your wet hair/scalp. Since the concern is fine/thinning hair, you might focus on root and scalp area where volume begins.
3. Lather and massage into scalp and through hair strands. Ensure you are aiding the scalp quite consciously, to cleanse and prep.
4. Rinse thoroughly.
5. For best results, follow with the matching Regeniplex Conditioner from the same line (or a conditioner suited for fine/thinning hair) to detangle and condition without weighing hair down. 
6. Style as usual. Because this product is targeting fullness and root area often, you may want to use styling techniques that lift hair (blow‑dry with root lift, use volumising products).
7. Frequency: Use each time you wash your hair (or according to your usual schedule). If your scalp/hair is sensitive or used to heavier treatments, you might alternate with a gentler wash.

Tips:

• If your hair is very dry and fine, you might need occasional richer treatments (mask or oil) on the lengths to maintain health while using this volumising/thinning‑hair focused shampoo.
• If using styling products often, ensure you occasionally clarify scalp (this shampoo claims to gently remove impurities).
• Since fragrance is quite described (lemon/basil/fir + mellow notes), if you are sensitive to fragrance, patch test first.
• Because formula targets thinning/fine hair, avoid heavy treatments at the scalp afterward (heavy concealer sprays, thick oils) that may counter the volume benefit.
