Hair loss has become a shared problem for women and men. One of the biggest questions is whether shed hair can grow back. Some turn to herbal oils, while others prefer medical treatments. Is there really anything that regrows hair?
In this guide, we examine evidence-based methods that can help hair grow again, common myths that seem effective but are not, and the frequent misconceptions about regrowth. We also look at the question not only as “is there a solution,” but also “which solution works for whom.”
Hair loss may be temporary in some people and permanent in others. The most critical factor is whether the follicles are still alive. If the follicles have not completely lost function, regrowth can occur with the right approach. If a follicle has died—no longer producing—new hair will not form. Therefore, identifying the type and cause of loss matters.
Underlying causes include genetic, hormonal, environmental, or lifestyle factors. In genetic loss, follicles gradually miniaturize and stop producing; early intervention may revive them. In temporary cases like stress, nutrient deficiencies, or seasonal changes, shedding is often reversible: the follicles are intact but in a “resting phase.”
For hair to start growing again, these conditions should be met:
It is a mistake to expect one solution to work for everyone. Hair structure, genetics, and lifestyle differ from person to person.
Several treatments with clinical evidence can support regrowth, provided they are applied to the right person at the right time. The main evidence-based options include:
PRP involves injecting plasma prepared from the patient’s own blood into the scalp via microinjections. Plasma is rich in growth factors that can revitalize follicles.
Microinjections of vitamins, minerals, amino acids, and specific blends into the scalp. Delivering ingredients beneath the skin helps nourish follicles.
An FDA-approved topical that supports regrowth; applied twice daily. Separate formulations exist for women and men.
Used only for male-pattern baldness. It protects follicles by suppressing the hormone DHT. Use strictly under medical supervision. Not recommended for women due to potential hormonal effects.
Low-level lasers stimulate follicles and increase cellular activity. Available as in-clinic or home-use devices.
Many products and methods are marketed with “regrows hair” claims, but most lack scientific basis. Avoid being misled. Frequent myths include:
Garlic may help cleanse microbes due to antibacterial properties, but there is no solid evidence it regrows hair. Direct application can burn or irritate the skin.
Onion juice may increase blood flow, yet it does not regrow hair on its own and can cause allergies in some people.
Natural oils like rosemary, coconut, and argan can nourish the scalp, but evidence for true regrowth is limited. Oils are supportive—not primary therapy.
False. Shaving does not affect the follicle structure. Hair growth rate and density are genetically determined.
Despite claims, shampoos do not penetrate to the follicles to stimulate growth. They may reduce shedding, but cannot regrow hair alone.
Hair health depends on adequate vitamins and minerals. Deficiencies commonly linked to shedding include:
Deficiencies deprive follicles of nutrients and can lead to loss. A simple blood test can identify them.
With appropriate treatment and support, follicles can become active again—though not in every case. If a follicle is completely destroyed, revival is not possible. Otherwise, therapies like PRP, mesotherapy, and LLLT may help restore productivity.
While they do not directly regrow hair, the following natural oils may support scalp health:
Oils are supportive only and cannot replace primary treatments.
A holistic approach works best:
Early medical intervention generally achieves better control of shedding.
