The order of shampoo, conditioner, and treatment can vary depending on individual hair care needs. However, a common order is to first shampoo the hair to cleanse it, then apply conditioner to moisturize and detangle, and finally use a treatment product for specific hair concerns such as deep conditioning or repairing damage. It's important to consider your hair type and specific needs when determining the best order for your hair care routine. **

For thin, fine, wavy hair with a slightly oily scalp and slightly dry hair, it's best to look for lightweight, volumizing products that won't weigh the hair down. A clarifying shampoo like Paul Mitchell Tea Tree Special Shampoo can help control oiliness, while a volumizing conditioner like OGX Biotin & Collagen Conditioner can add body without adding excess weight. For hair oil, a lightweight, nourishing option like Moroccanoil Treatment Light can help hydrate the dry ends without making the scalp too oily. **

If changing your shampoo and conditioner hasn't helped with your itchy scalp, there are a few other steps you can take. First, try using a gentle, fragrance-free shampoo and conditioner to avoid any potential irritants. You can also try using a scalp treatment or oil to help soothe and moisturize your scalp. Additionally, make sure you are not washing your hair too frequently, as this can strip the scalp of its natural oils and contribute to itching. If the itching persists, it's best to consult a dermatologist to rule out any underlying skin conditions. **
