Hair Growth Tips: What Actually Works

Everyone who has ever cut their hair shorter than intended — or made a bold change and immediately missed their length — has experienced the frustration of waiting for hair to grow back. You do the conditioning treatments. You use professional products. You get your trims. And still, the growth feels impossibly slow. The reason often lies not in what you’re doing at the salon, but in what you’re doing everywhere else. Here is what the research and our experience at Aurelio Salon & Spa in Howell, NJ suggest actually works for hair growth.

Protein Is the Foundation

Hair is composed almost entirely of keratin — a protein. If your diet is consistently low in protein, your hair will be among the first things to show it. The body treats hair as a non-essential tissue and prioritizes vital organs when nutrients are limited — meaning the hair only gets what is left over. A protein deficiency manifests as slow growth, increased shedding, and hair that breaks before it reaches any real length. Prioritizing complete proteins — eggs, lean meats, fish, legumes — gives your hair the building blocks it needs to grow and stay strong.

Healthy Fats for Moisture and Shine

Lipids — healthy fats — are essential for maintaining the moisture and shine of the hair. They are found in avocados, olive oil, whole milk, cheese, fatty fish, and nuts. A diet consistently low in healthy fats often shows up as dry, dull, brittle hair that is prone to breakage — which limits length retention even when the hair is technically growing at a normal rate.

Iron for Growth and Retention

Iron deficiency is one of the most common nutritional causes of hair loss and slow growth, particularly in women. Iron supports the production of hemoglobin, which carries oxygen to the hair follicle — a process that is essential for healthy growth. Good dietary sources include clams, beans, lentils, fortified grains, and leafy greens. Pairing iron-rich foods with vitamin C sources improves absorption significantly.

Exercise Improves Scalp Circulation

Regular cardiovascular exercise improves circulation throughout the body — including to the scalp. Better scalp circulation means more efficient nutrient delivery to the hair follicle, which directly supports growth rate and hair density. This is one of the most overlooked aspects of hair growth and one of the simplest to address.

Protect the Length You Have

Hair growth is only half the equation — retaining that growth is the other half. Hair that grows but breaks off at the same rate will never get longer. Regular trims to remove split ends, protective styling, reduced heat usage, and professional conditioning treatments all help preserve length. Ask your stylist at your next visit about a treatment plan that supports both growth and retention for your hair type.
