Most of us have a shelf full of products we shouldn't have bought. The point of this page is to help you buy fewer things — by sorting picks by porosity and routine instead of by hype.
| Porosity | What it often needs | Avoid |
|---|---|---|
| Low porosity | Light leave-ins, water-based products, gentle heat with deep conditioning. | Too much butter/oil layering. |
| Normal porosity | Balanced moisture, regular masks, flexible routines. | Changing products too often. |
| High porosity | Richer leave-ins, sealing, protein when needed, careful strengthening. | Skipping sealing or overusing protein. |
Filter by porosity, scalp care, or DIY ingredients. Every link goes to Amazon — see the disclosure at the bottom.
Base ingredients for natural hair recipes: sprays, masks, oils, pre-poos, and styling gels.
